Abstract

A non-volatile (NV) memory write method using data protection with aid of pre-calculation information rotation, and associated equipment such as memory device, controller and encoding circuit thereofare provided. The NV memory write method may include: receiving a write command and data from a host device; obtaining at least one portion of data to be a plurality of messages, to generate a plurality of parity codes through pre-calculation information rotation type encoding, wherein regarding a message: starting encoding a message to calculate a partial parity code according to the message anda transpose matrix of a part-one matrix within a parity check matrix; loading a partial matrix of an inverse matrix of a part-two matrix within the parity check matrix from a storage circuit; applyingthe partial matrix and its rotated version(s) generated through rotation control to generate and output a corresponding parity code; and writing into the NV memory. According to the method and the equipment, the memory device is ensured to properly operate under various conditions, and the problems of internal storage space, cost increase and the like are solved.

Description

technical field [0001] The present invention relates to memory control, and more particularly to a non-volatile (non-volatile, NV) memory writing method using data protection by means of precalculated information rotation (rotation) and related equipment such as a memory device, said memory A controller of the device, and an encoding circuit of the controller. Background technique [0002] Due to the continuous development of memory technology in recent years, various portable and non-portable memory devices (for example: memory cards that meet SD / MMC, CF, MS, XD and UFS standards respectively; and for example: solid state drives (solid state drives) state drive, SSD); another example: embedded (embedded) storage devices conforming to UFS and EMMC standards respectively) are widely implemented in many applications. Therefore, access control of memories in these memory devices has become a very hot topic. [0003] For commonly used NAND flash memory, it mainly includes two ...
