METHOD FOR SHARED DISTRIBUTED MEMORY MANAGEMENT IN MULTI-CORE SOLID STATE DRIVE (SSD)

摘要

ABSTRACT Method and system for memory access in a multi-core Solid State Drive (SSD). In this method, Direct Memory Access (DMA) descriptors are distributed to local memory of each processor, and a DMA engine is configured with logical addresses corresponding to location of the DMA descriptors. The DMA engine is configured to receive a memory access request from a server, extract a logical address of the memory location indicated in the received request, and determine physical address of the memory location by processing a logical address that is extracted from a data request received.The logical addresses emulate a continuous memory while the data is stored in different memory locations.
