The Processing Using Memory Paradigm:In-DRAM Bulk Copy, Initialization, Bitwise AND and OR

Understand

In existing systems, the off-chip memory interface allows the memory controller to perform only read or write operations.

• Therefore, to perform any operation, the processor must first read the source data and then write the result back to memory after performing the operation.
• This approach consumes high latency, bandwidth, and energy for operations that work on a large amount of data.
• Several works have proposed techniques to process data near memory by adding a small amount of compute logic closer to the main memory chips.
