A first master receives a first virtual address in a virtual memory, the first virtual address in the virtual memory corresponding, according to a mapping function, to a first physical address of a first physical memory bank which is to be accessed by the first master. The first master accesses the first physical address to perform a first memory operation in the first memory bank. A second master receives a second virtual address in a virtual memory, the second virtual address in the virtual memory corresponding, according to the mapping function, to a second physical address of a second physical memory bank which is to be accessed by the second master. Concurrently with access by the first master to the first physical address, the second master accesses the second physical address to perform a second memory operation in the second physical memory bank.

A memory system includes: a memory block including a plurality of pages each comprising a plurality of memory cells connected to bit lines and a word line of word lines, an address manager configured to output addresses corresponding to the plurality of pages, and a system data manager configured to generate index data corresponding to the each of the addresses, the index data indicating whether user data is inverted, and output the index data and information on a memory cell in which the index data is to be stored, respectively. The system data manager is configured to, determine memory cells connected to different bit lines from among memory cells included in adjacent pages corresponding to consecutive addresses of the addresses, as memory cells in which index data corresponding to the consecutive addresses are to be stored.

A memory controller receives, via a first interface, a first read request requesting a requested data granule. Based on receipt of the first read request, the memory controller transmits, via a second interface, a second read request to initiate access of the requested data granule from a system memory. Based on a determination to schedule accelerated data delivery and receipt by the memory controller of a data scheduling indication that indicates a timing of future delivery of the requested data granule, the memory controller requests, prior to receipt of the requested data granule, permission to transmit the requested data granule on the system interconnect fabric. Based on receipt of the requested data granule at the indicated timing and a grant of the permission to transmit, the memory controller initiates transmission of the requested data granule on the system interconnect fabric and transmits an error indication for the requested data granule.

An integrated circuit (IC) includes a memory manager having a plurality of memory ports, each configured to communicate with a corresponding floating memory block. The IC includes a first interconnect for a first domain, wherein the first interconnect has a first set of fixed ports configured to communicate with memory blocks dedicated to the first domain and a first set of floating ports configured to communicate with the memory manager, and a second interconnect for a second domain, wherein the second interconnect has a second set of fixed ports configured to communicate with memory blocks dedicated to the second domain and a second set of floating ports configured to communicate with the memory manager. The memory manager is configured to allocate a first portion of the memory ports to the first set of floating ports and a second portion of the memory ports to the second set of floating ports.

A multi-chip package includes a logic integrated circuit (IC) die formed with plural memory controller circuits, a first memory IC die and a second memory IC die. The second memory IC die is mounted to the first memory IC die. The first memory IC die and the logic IC die are mounted to one another. The logic IC die includes a serial link interface for coupling to multiple serial links. The first memory die includes a first memory group accessed by a first one of the plural memory controller circuits, and a second memory group accessed by a second one of the plural memory controller circuits.

In some embodiments, an integrated circuit may include a substrate and a memory array disposed on the substrate, where the memory array includes a plurality of discrete memory banks. The integrated circuit may also include a processing array disposed on the substrate, where the processing array includes a plurality of processor subunits, each one of the plurality of processor subunits being associated with one or more discrete memory banks among the plurality of discrete memory banks. The integrated circuit may also include a controller configured to implement at least one security measure with respect to an operation of the integrated circuit and take one or more remedial actions if the at least one security measure is triggered.

A system enables entities to access a single platform in order to utilize electronic data storage for storing different types of information. One or more computers may operate an electronic data storage processing network that entities can access when updating information in electronic data storage. The electronic data storage processing network may operate a plurality of electronic data storage processing modules, which can include an aggregator module, a formatter module, an operator signer module, and a validator module. Based on the specific use case for which electronic data storage is utilized, recordable data that is to be added to the electronic data storage can be processed by the appropriate aggregating, formatting, signing, and validating functions provided by the electronic data storage processing modules.

A queuing requester for access to a memory system is provided. Transaction requests are received from two or more requestors for access to the memory system. Each transaction request includes an associated priority value. A request queue of the received transaction requests is formed in the queuing requester. Each transaction request includes an associated priority value. A highest priority value of all pending transaction requests within the request queue is determined. An elevated priority value is selected when the highest priority value is higher than the priority value of an oldest transaction request in the request queue; otherwise the priority value of the oldest transaction request is selected. The oldest transaction request in the request queue with the selected priority value is then provided to the memory system. An arbitration contest with other requesters for access to the memory system is performed using the selected priority value.

Methods, systems, and devices for input/output line sharing for memory subarrays are described. I/O lines may be shared across subarrays, which may correspond to separate memory tiles. The sharing of I/O lines may allow an I/O line to carry data from one subarray in response to access commands associated with one address range, and to carry data from another subarray in response to access commands associated with another address range. In some cases, sense amplifiers and other components may also be shared across subarrays, including across subarrays in different banks. The sharing of I/O lines may, in some cases, support activating only a subset of subarrays in a bank when accessing data stored in the bank, which may provide power savings.

An MMI interface device and a computing system based thereon. An output MMI interface device is a device located between a master processor and a slave processor to exchange data between the master processor and the slave processor in an asynchronous manner, and includes a first memory bank that stores a large amount of data, a second memory bank that stores a large amount of data, and an RBM located between the first memory bank and the second memory bank and configured to determine a memory bank to be used by the master processor and a memory bank to be used by the slave processor, and connect a bus to each of the first memory bank and the second memory bank according to the determination so that the first memory bank and the second memory bank alternately output data from the master processor to the slave processor.
