METHOD AND DEVICE FOR CONSTRUCTING HIGH SPEED SOLID STATE STORAGE DISK WITH LARGER CAPACITY DRAM INVOLVED IN MANAGEMENT OF FLASH MEDIA

摘要

A high speed solid state storage disk device constructed with larger capacity DRAM involved in management of flash media, which used as a storage device of computers or servers includes a flash media module and an interface circuit module, and especially includes a larger capacity dynamic random memory DRAM module and a hard disk controller with DARM involved in management of flash media, and a double electric backup management module required by the DRAM module. The hard disk controller with DRAM involved in management of flash media is respectively coupled to the DRAM module and the flash media module through an address/data bus. The hard disk controller with DRAM involved in management of flash media is coupled to the interface circuit module through a composite bus. The double electric backup management module is electrically coupled to the hard disk controller with DRAM involved in management of flash media.
