Embodiment Construction

[0025] For convenience, the same reference numerals in the description refer to the same structures in the drawings. see figure 1 , generally indicated at 100 is a block diagram of a solid state memory system. Solid state memory system 100 includes memory controller 102 and solid state memory 104 . External device 106 communicates with solid-state memory 104 through memory controller 102 .

[0026] In this embodiment, memory controller 102 includes virtual mapping system 108 (or simply mapping system 108 ). Mapping system 108 is used to map logical addresses associated with requests to physical addresses associated with solid state storage 104 .

[0027] Solid-state memory 104 includes volatile memory 104a and non-volatile memory 104b. It will be appreciated that volatile memory 104a and non-volatile memory 104b may include one or more memory devices.

[0028] In this embodiment, the volatile memory 104a includes DRAM memory and the non-volatile memory 104b includes NAND ...

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 the volatile 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

[0001] This application is a divisional application of the application number 200780046944.0, the filing date is December 18, 2007, and the invention title is "Hybrid solid-state memory system with volatile and non-volatile memory". technical field [0002] The present invention relates generally to solid-state memory systems, and more particularly, the present invention relates to hybrid solid-state memory systems including volatile and non-volatile memory. Background technique [0003] 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. [0004] Solid state memory is a data storage device that uses memory chips to ...
