ParaBit: Processing Parallel Bitwise Operations in NAND Flash Memory based SSDs

Processing-in-memory (PIM) and in-storage-computing (ISC) architectures have been constructed to implement computation inside memory and near storage, respectively. While effectively mitigating the overhead of data movement from memory and storage to the processor, due to the limited bandwidth of existing systems, these architectures still suffer from the large data movement overhead between storage and memory, in particular, if the amount of required data is large. It has become a major constraint for further improving the computation efficiency in PIM and ISC architectures.
