A storage system and method for host memory access are provided. In one embodiment, a storage system is provided comprising a memory and a controller. The controller is configured to receive a write command from the host that is recognized by the storage system as a read host memory command; in response to receiving the write command, send an identification of a location in the host memory to the host; and receive, from the host, data that is stored in the location in the host memory. Other embodiments are provided.

Technologies for scrambling functions in a column-addressable memory architecture includes a device having a memory and a circuitry. The memory includes a matrix storing individually addressable bit data, and the matrix is formed by rows and columns. The circuitry is to receive a request to perform a write operation of one or more bit values to one of the columns. The circuitry is further to determine a scrambler state at each location of the column, the location corresponding to a respective row and column index. The scrambler state is indicative of a function used to determine a value at the respective column location. Each of the bit values is scrambled as a function of the scrambler state for the respective column location and written thereto.

A memory device includes: a memory array used for implementing neural networks (NN), the NN including a plurality of layers; and a controller coupled to the memory array, the controller being configured for: determining a computation duration of a first data of a first layer of the plurality of layers; selecting a first program operation if the computation duration of the first data of the first layer is shorter than a threshold; and selecting a second program operation if the computation duration of the first data of the first layer is longer than the threshold, wherein the second program operation has a longer program pulse time than the first program operation.

A data storage device and method for low-latency power state transitions by having power islanding in a host memory buffer are provided. In one embodiment, a data storage device is provided comprising a volatile memory, a non-volatile memory, and a controller. The controller is configured to receive information from a host about which area, if any, in a host memory buffer will be powered on during a low-power state; and in response to the information indicating that a first area of the host memory buffer will be powered on during the low-power state, flush data from a second area of the host memory buffer that will not be powered on during the low-power state to the first area of the host memory buffer prior to entering the low-power state. Other embodiments are provided.

A memory access method and a computer system are provided. According to the memory access method, whether to flip the to-be-stored data for storage may be determined based on quantities of “1” and “0” in data to be written into a dynamic random access memory (DRAM) and a storage mode of the DRAM, to reduce a quantity of storage cells with high electric charges in the DRAM, thereby reducing a data error probability.

A memory device includes a memory cell array and a peripheral circuit. The memory cell array includes a plurality of memory regions each identified by a row address and a column address. The peripheral circuit accesses the memory cell array by performing, based on an address, a burst length and a burst address gap provided from a memory controller, a burst operation supporting a variable burst address gap. The burst address gap is a numerical difference between adjacent column addresses, on which the burst operation is to be performed.

The present disclosure includes apparatuses and methods related to shifting data. An example apparatus comprises a cache coupled to an array of memory cells and a controller. The controller is configured to perform a first operation beginning at a first address to transfer data from the array of memory cells to the cache, and perform a second operation concurrently with the first operation, the second operation beginning at a second address.

Methods, systems, and devices for using page line filler data are described. In some examples, a memory system may store data within a write buffer of the memory system. The memory system may initiate an operation to transfer the write buffer data to a memory device, for example, due to a command to perform a memory management operation (e.g., cache synchronization, context switching, or the like) from a host system. In some examples, a quantity of write buffer data may fail to satisfy a data size threshold. Thus, the memory system may aggregate the data in the write buffer with valid data from a block of the memory device associated with garbage collection. The memory system may aggregate the write buffer data with the garbage collection data until the aggregated data satisfies the data size threshold. The memory system may then write the aggregated data to the memory device.

A storage system includes a host including a processor and a memory unit, and a storage device including a controller and a non-volatile memory unit. The processor is configured to output a write command, write data, and size information of the write data, to the storage device, the write command that is output not including a write address. The controller is configured to determine a physical write location of the non-volatile memory unit in which the write data are to be written, based on the write command and the size information, write the write data in the physical write location of the non-volatile memory unit, and output the physical write location to the host. The processor is further configured to generate, in the memory unit, mapping information between an identifier of the write data and the physical write location.

A mechanism is described for facilitating using of a shared local memory for register spilling/filling relating to graphics processors at computing devices. A method of embodiments, as described herein, includes reserving one or more spaces of a shared local memory (SLM) to perform one or more of spilling and filling relating to registers associated with a graphics processor of a computing device.
