Abstract

See full text

A processor-based system includes a processor coupled to core logic through a processor bus. This includes a dynamic random access memory (“DRAM”) memory buffer controller. The DRAM memory buffer controller is coupled through a memory bus to a plurality of a dynamic random access memory (“DRAM”) modules and a flash memory module, which are at the same hierarchical level from the processor. Each of the DRAM modules includes a memory buffer to the memory bus and to a plurality of dynamic random access memory devices. The flash memory module includes a flash memory buffer coupled to the memory bus and to at least one flash memory device. The flash memory buffer includes a DRAM-to-flash memory converter operable to convert the DRAM memory requests to flash memory requests, which are then applied to the flash memory device.
