System and Method for Distributed Computing in Non-Volatile Memory

摘要

A system and method are disclosed for incorporating mathematical and/or logical functionality within a memory system (such as a solid state drive (SSD)). The mathematical and/or logical functionality may comprise an arithmetic logic unit (ALU). The ALU may be resident in one or both of flash memory chips or the SSD controller. When resident in the flash memory chips, a single ALU or multiple ALUs may be used. For example, a single ALU may be assigned to one, some, or each block of flash memory within the flash memory chip. As another example, an ALU may be assigned to a sub-block construct, such as to each bit line in the block. Having ALUs resident in the SSD enables more processing to be performed within the SSD and reduces the need to transmit data outside of the SSD for processing.

主权项

1. A solid state device (SSD) comprising:
a communication interface configured to communicate with a host device; a memory; and at least one controller in communication the communication interface and the memory, and configured to:
receive a write command from the host device, the write command comprising one or more values;in response to receiving the write command, cause storage of the one or more values in the memory;receive a command from the host device;in response to receiving the command, use mathematical computation functionality or logic functionality in the SSD on the one or more values previously stored in the memory in order to generate one or more results; andsend to the host device at least a part of the one or more results or an indication of the one or more results.
