A system on-chip includes a central processing unit and a memory controller. The memory controller receives initialization information indicating an initialization address range and an initialization value from the central processing unit, determines an initialization target memory and a local initialization address range of the initialization target memory based on the initialization information, and transmits initialization data including the initialization value to the initialization target memory by a predetermined unit to initialize the local initialization address range of the initialization target memory.

Profiling cache replacement is a technique for managing data migration between a main memory and a cache memory to improve overall system performance. A profiler maintains counters that count memory requests for access to the pages maintained in both the cache memory and the main memory. Based on this access-request count information, a mover moves pages between the main and cache memories. For example, the mover can swap little-requested pages of the cache memory with highly-requested pages of the main memory. The mover can do so, for instance, when the counters indicate that the number of page access requests for highly-requested pages of the main memory is greater than the number of page access requests for little-requested pages of the cache memory. To avoid impeding the operations of memory users, the mover can perform page swapping in the background at predetermined time intervals, such as once every microsecond (s).

There is provided a method for updating an internal memory on a semiconductor device from an external memory. The external memory is arranged in a plurality of data portions.

Technologies for field-programmable gate array (FPGA) processing include a computing device having a field-programmable gate array (FPGA) and a virtual FPGA controller (VFC). The computing device generates a user-specific platform profile (PP) that identifies one or more FPGA applications to be instantiated. The computing device synthesizes each FPGA application identified by the PP to generate a bit stream image that is associated with the PP and saves the bit stream image in a profile storage of the computing device. The computing device generates a virtual memory address that is indicative of the identified FPGA applications in response to saving the bit stream image. The VFC translates the virtual memory address to a user segment of the FPGA and a logical element (LE) offset within the user segment. The FPGA executes the bit stream associated with the PP with the FPGA at the LE offset. Other embodiments are described and claimed.

Provided are a method and apparatus for remapping logical to physical addresses for a non-volatile memory having dies. Bands extend through the dies and planes in the dies extending through the bands define addressable blocks. A first remapping of a logical-to-physical mapping is performed by remapping logical addresses of blocks in a first end of the bands that map to defective physical blocks to map to good physical blocks at a second end of the bands. After performing the first remapping, a second remapping of the logical-to-physical mapping is performed by remapping logical addresses in the second end of bands that map to defective blocks to map to good physical blocks in the first end of bands.

Methods, apparatuses, and systems for tensor memory access are described. Multiple data located in different physical addresses of memory may be concurrently read or written by, for example, employing various processing patterns of tensor or matrix related computations. A memory controller, which may comprise a data address generator, may be configured to generate a sequence of memory addresses for a memory access operation based on a starting address and a dimension of a tensor or matrix. At least one dimension of a tensor or matrix may correspond to a row, a column, a diagonal, a determinant, or an Nth dimension of the tensor or matrix. The memory controller may also comprise a buffer configured to read and write the data generated from or according to a sequence of memory of addresses.
