Hybrid solid-state memory system having volatile and non-volatile memory

Abstract

A hybrid solid-state memory system is provided for storing data. The solid-state memory system comprises a volatile solid-state memory, a non-volatile solid-state memory, and a memory controller. Further, a method is provided for storing data in the solid-state memory system. The method comprises the following steps. A write command is received by the memory controller. Write data is stored in thevolatile memory in response to the write command. Data is transferred from the volatile memory to the non-volatile memory in response to a data transfer request.

Description

technical field [0001] [0001] The present invention relates generally to solid-state memory systems, and more particularly, the present invention relates to hybrid solid-state memory systems that include volatile and non-volatile memory. Background technique [0002] [0002] The most common mass storage system in current computer systems is a hard disk drive (HDD) that uses one or more spinning platters and records data magnetically. Although HDDs are capable of storing large amounts of information, they have many disadvantages compared to solid-state memory. Specifically, HDDs have low read / write speed, high power consumption, large system size, and low mechanical shock resistance. [0003] [0003] Solid state memory is a data storage device that uses memory chips to hold data. Non-volatile solid-state memories such as flash memory, for example, are becoming increasingly common as their storage densities increase. It is foreseeable that due to the advantages of solid state...
