Abstract

A control device of non-volatile storage, and a method and a system thereof for dispatching data are used for controlling a multi-layer storage to store data. The control device comprises a controllerand a dispatching module. The controller is used for transmitting a request signal to the dispatching module after transmitting a command to a current storage unit block of the multi-layer storage. The request signal is a command that is requested, by the controller, to transmit through the dispatching module in connection with next storage unit block when the current storage unit block is in a latent period. The controller transmits a state query command to the storage when the current storage unit block finishes the latent period, receives the state information fed back by the storage according to the state query command, and reports the state information to the dispatching module. The controller in the invention requests the dispatching module to transmit a command in connection with next storage unit block when the current storage unit block is in the latent period so as to improve the data processing speed of the storage.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a nonvolatile memory control device, a data scheduling method and a system thereof. Background technique [0002] NVRAM (Non-Volatile Random Access Memory) is a non-volatile random access memory, which is characterized in that the data does not disappear after the memory is powered off, and the data can still be saved. A type of MLC (Multi Level Cell, multi-level memory) in the current NVRAM memory stores 2 Bit or more Bit data in each storage unit by using a large number of voltage levels. Because of its high data density and low cost, it has been widely used. [0003] The operations on the MLC type NVRAM memory are mainly read, write and delete. Each piece of NVRAM memory is internally divided into several block layers (memory unit blocks), and the operations between each layer are independent of each other. Blocks of memory cells called layers can be erased and reprogrammed as s...
