An information handling apparatus includes a controller, a memory coupled to the controller, the memory having a persistent region that can either be locked or unlocked, and a firmware configured to determine whether the persistent region of the memory is locked, obtain a stored passphrase from a storage device if the persistent region is locked, and use the passphrase to unlock the persistent region of the memory.

An automated storage unit publishing system may include a recording device for recording information on a storage unit memory chip; a bin plate with a storage unit bin and a casing bin; an assembling mechanism movably attached to the bin plate, the assembling deck comprising a shuttle for removing a selected sized casing from the casing bin and a recorded flash memory chip from the chip bin and assembling the two into a single unit using pressure; a printing device for printing marks, indications or decoration on the casing, and a gripping device for placing the finished unit in an output mechanism.

A method of processing in-memory commands in a high-bandwidth memory (HBM) system includes sending a function-in-HBM instruction to the HBM by a HBM memory controller of a GPU. A logic component of the HBM receives the FIM instruction and coordinates the instructions execution using the controller, an ALU, and a SRAM located on the logic component.

A data transmission method applied to an APB bridge for connecting an APB and an AHB, includes: dividing transmission into an address phase and a data phase according to a feature of an AHB; in the address phase, when the AHB meets an address transmission condition corresponding to a current operation, transmitting address information and control information, which are sent by the AHB, to an APB; and in the data phase, when the APB meets a valid data transmission condition corresponding to the current operation, sending received data to a bus corresponding to the current operation, wherein the bus is the APB or the AHB. According to the present application, the address information, the control information, and the data do not need to be cached, whereby the occupation of a storage space is reduced. Further disclosed are a data transmission apparatus and an electronic device having the above beneficial effects.

Each storage controller comprises a first storage unit, an interface unit, and a processing unit which sends, to the interface unit, a parameter which instructs n-fold write of writing data in each of n-number of (n is a natural number of 2 or more) other storage controllers. When the interface unit receives the parameter, the interface unit executes each processing of acquiring the data from the first storage unit and storing the data in the second storage unit, generating n-number of requests of writing the data in each of n-number of the other storage controllers, storing each of the generated requests in n-number of the queues corresponding to each of n-number of the other storage controllers, and processing each request stored in each queue and transferring the data stored in the second storage unit to each of n-number of the other storage controllers.

Methods, systems, and apparatuses provide support for multiple address spaces in order to facilitate data movement. One system includes a host processor; a memory; a data fabric coupled to the host processor and to the memory; a first input/output memory manage unit (IOMMU) and a second IOMMU, each of the first and second IOMMUs coupled to the data fabric; a first root port and a second root port, each of the first and second root ports coupled to a corresponding IOMMU of the first and second IOMMUs; and a first peripheral component endpoint and a second peripheral component endpoint, each of the first and second peripheral component endpoints coupled to a corresponding root port of the first and second root ports, wherein each of the first and second root ports comprises hardware control logic operative to: synchronize the first and second root ports.

The present disclosure includes apparatuses and methods for in data path compute operations. An example apparatus includes an array of memory cells. Sensing circuitry is selectably coupled to the array. A plurality of shared input/output (I/O) lines provides a data path. The plurality of shared I/O lines selectably couples a first subrow of a row of the array via the sensing circuitry to a first compute component in the data path to move a first data value from the first subrow to the first compute component and a second subrow of the respective row via the sensing circuitry to a second compute component to move a second data value from the second subrow to the second compute component. An operation is performed on the first data value from the first subrow using the first compute component substantially simultaneously with movement of the second data value from the second subrow to the second compute component.

To reduce direct memory access (DMA) overhead, a tensorized descriptor can be used to generate a series of memory descriptors to perform a series of DMA data transfers. The tensorized descriptor may include attributes such as a stride and a memory descriptor template, which can be used to generate the series of memory descriptors. Hence, instead of having to retrieve each of the memory descriptors to perform the series of DMA transfers, a single tensorized descriptor can be retrieved to perform a series of data transfers.

Memory access control circuitry controls handling of a memory access request based on at least one memory access control attribute associated with a region of address space including the target address. The memory access control circuitry comprises: lookup circuitry comprising a plurality of sets of comparison circuitry, each set of comparison circuitry to detect, based on at least one address-region-indicating parameter associated with a corresponding region of address space, whether the target address is within the corresponding region of address space; region mismatch prediction circuitry to provide a region mismatch prediction indicative of which of the sets of comparison circuitry is predicted to detect a region mismatch condition; and comparison disabling circuitry to disable at least one of the sets of comparison circuitry that is predicted by the region mismatch prediction circuitry to detect the region mismatch condition for the target address.

Apparatuses and methods including memory commands for semiconductor memories are described. A controller provides a memory system with memory commands to access memory. The commands are decoded to provide internal signals and commands for performing operations, such as operations to access the memory array. The memory commands provided for accessing memory may include timing command and access commands. Examples of access commands include a read command and a write command. Timing commands may be used to control the timing of various operations, for example, for a corresponding access command. The timing commands may include opcodes that set various modes of operation during an associated access operation for an access command.
