Abstract
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.
