METHOD OF DIRECT CONNECTING AHCI OR NVMe BASED SSD SYSTEM TO COMPUTER SYSTEM MEMORY BUS

Abstract

A SSD system directly connected to the system memory bus includes at least one system memory bus interface unit, one storage controller with associated data buffer/cache, one data interconnect unit, one nonvolatile memory (NVM) module, and flexible association between storage commands and the NVM module. A logical device interface, the Advanced Host Controller Interface (AHCI) or NVM Express (NVMe), is used for the SSD system programming. The SSD system appears to the computer system physically as a dual-inline-memory module (DIMM) attached to the system memory controller, and logically as an AHCI device or an NVMe device. The SSD system may sit in a DIMM socket and scaling with the number of DIMM sockets available to the SSD applications. The invention moves the SSD system from I/O domain to the system memory domain.
