Example Embodiment

[0020] FIG. 2 is a schematic diagram of a non-volatile memory device according to a first embodiment of the present invention. Please refer to FIG. 2 , the non-volatile memory device 11 provided by the present invention is, for example, a flash memory or other memories. The non-volatile memory device 11 of the present invention may include a data access circuit 40 and a plurality of memory blocks, such as 31, 32 and 3n. In this embodiment, the data access circuit 40 is coupled to the memory blocks 31, 32 and 3n. The data access circuit 40 can utilize the memory blocks 31, 32 and 3n for data access.

[0021] The data access circuit 40 includes a main controller 20 and a plurality of sub-controllers, such as 21, 22 and 2n. Wherein, the sub-controllers 21, 22 and 2n are correspondingly coupled to the storage blocks 31, 32 and 3n. Thereby, the main controller 20 can assign tasks to the sub-controllers 21 , 22 and 2n respectively, and the sub-controllers 21 , 22 and 2n can use t...

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...
