Storage controller

Abstract

The invention discloses a storage controller, comprising a host interface module, a reconfiguration module, a cache controller, a storage equipment controller, a processor and a reconfigurable module, wherein the host interface module is used for transmitting a command and data between the storage controller and a host; the reconfiguration module is used for reconfiguring the reconfigurable module according to a configuration file after the host interface module receives a reconfiguration command; the cache controller is used for controlling read-write of a cache of an equipment terminal; the storage equipment controller is used for controlling the read-write of various storage equipment or storage devices; the processor is used for executing a control program related to the command received by the host interface module; and the reconfigurable module is used for reconfiguration through a reconfiguration mode according to needs. By use of the storage controller, the computer system performance can be improved.

Description

technical field [0001] The invention belongs to the technical field of computer storage, and more specifically relates to a storage controller. Background technique [0002] With the new non-volatile memory (Non-Volatile Memory, NVM), such as phase change memory (PhaseChange Memory, PCM), spin transfer torque random access memory (Spin Transfer Torque Random AccessMemory, STT-RAM), resistive change memory ( The emergence of Resistive Random Access Memory (RRAM), etc. has brought new changes and challenges to computer systems. These new non-volatile memories use mechanisms such as phase change effect, magnetoresistance effect, and resistive change effect to store data. Compared with traditional memory devices, they have the advantages of high storage density, short read and write delays, and low energy consumption. Due to their many advantages, new types of non-volatile memory are gradually becoming the most important part of the storage architecture. [0003] As the new no...
