[0038] According to the first embodiment of the present invention, when the control circuit 101 stores the write data into the memory cell array 105, the write data will be stored in the first part of the logical block, that is, stored in the 8 pages of the logical block . In addition, the control circuit 101 will calculate the data of the 8 pages of the logical block to generate a parity page and store it in a page of the second part of the logical block.

[0039] Please refer to FIG. 4, for example, when the control circuit 101 stores the write data of the host computer 14 into the memory cell array 105, the write data will be stored in 8 pages in the wth logic block, that is, P0-P7 . In addition, the control circuit 101 calculates the data of the 8 pages of the wth logical block to generate a parity page and store it in a page of the yth logical block, such as PP0.

[0040] For example, the control circuit 101 uses the output value of the first bit of the 8 pages (P0-P7) ...

Abstract

The invention discloses a data solid-state storage device and a related data management method thereof. The solid-state storage device comprises a memory cell array, the memory cell array is divided into a plurality of logic blocks of a first part and a plurality of logic blocks of a second part, and the data management method comprises the following steps of storing multi-page write-in data provided by a host into the first logic block of the first part; performing an operation on the write-in data of the pages provided by the host, and obtaining a parity check page; and storing the parity check page in a second logic block of the second part.

Description

technical field [0001] The present invention relates to a solid state storage device and its related control method, and in particular to a solid state storage device and its related data management method. Background technique [0002] As we all know, solid state storage device (solid state device) has been widely used in various electronic products, such as SD card, solid state hard disk and so on. Generally speaking, a solid-state storage device is composed of a control circuit and a non-volatile memory. Furthermore, the solid-state storage device can also be called a flash memory (flash memory). [0003] Please refer to figure 1 , which is a schematic diagram of a solid-state storage device. The solid state storage device 10 includes: a control circuit 101 and a memory cell array 105 . [0004] The solid-state storage device 10 is connected to a host 14 via an external bus 12, wherein the external bus 12 can be a USB bus, a SATA bus, a PCIe bus, and the like. Furthe...
