Non-volatile memory device and data access circuit and method thereof

Abstract

The invention discloses a nonvolatile memory device, and an access circuit and a method of data. The nonvolatile memory device comprises a main controller, a plurality of sub-controllers and a plurality of storage blocks. The sub-controllers are coupled with the main controller and used for executing tasks dispatched by the main controller. The storage blocks are respectively coupled with the sub-controllers correspondingly. Furthermore, the main controller is used for dividing received main data into a plurality of sub-data and respectively storing the first sub-data into the storage blocks by the sub-controllers. Therefore, the data access speed of the nonvolatile memory device can be greatly promoted.

Description

technical field [0001] The present invention relates to a data access technology, and in particular to a data access technology of a non-volatile memory device. Background technique [0002] The types of traditional semiconductor memory (Memory) can be roughly divided into two types: non-volatile (Non-volatile) memory and volatile (Random Access Memory, "RAM") . Among them, the non-volatile memory means that the original stored data can be preserved after the power supply is interrupted, such as read-only memory (Read Only Memory, ROM for short), programmable read-only memory (Programmable ROM, PROM for short), erasable Programmable read-only memory (Erasable PROM, referred to as EPROM), electrically erasable programmable read-only memory (Electrically Erasable PROM, referred to as EEPROM), mask read-only memory (Mask ROM) and flash memory (Flash memory)...etc. . [0003] Volatile memory means that the stored data will disappear when the power is interrupted. For example...

Problems solved by technology

However, the traditional flash memory 10 not only has a slow data access speed, but once some data is lost or damaged, the data cannot be output.
