Embodiment Construction

[0016] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and through specific embodiments.

[0017] like figure 1 The schematic diagram of the non-volatile storage medium control module is shown. In this embodiment, the non-volatile storage medium control module 150 not only includes: a coprocessor 1503 and a data storage 1502, but also includes: a first random access memory 1501 and a second random access memory 1501 Two RAM 1504. The instructions sent by the host system are transmitted to the main control processor 13 through the interface controller, and the main control processor is based on the medium configuration information stored in the read-only memory 12, such as: the array characteristics of the flash memory medium, the instruction operation information of the flash memory medium, etc., The host instruction is parsed into a corresponding medium control instruction and sent to the first rando...

Abstract

The invention discloses a non-volatile memory medium controller and a non-volatile memory device. In the invention, a secondary processing host instruction method is adopted, namely, a co-processor is arranged in a control module of a controller to analyze a medium control instruction into a medium operation instruction, and configuration information (characteristic information, etc.) of a non-volatile memory medium is configured and stored in a read-only memory of the memory device beforehand, thereby greatly improving the configurability of the controller and the memory device and instruction processing efficiency. In addition, the parallel processing among the multiple control modules and the parallel processing of a medium chip instruction are realized by arranging a plurality of control modules in the controller and an instruction cache mechanism in the multiple control modules, thereby realizing high speed of medium operation and data transmission.

Description

technical field [0001] The invention relates to a compatibility control technology of a non-volatile storage medium. Background technique [0002] With the gradual promotion of the application of various non-volatile storage media, more and more manufacturers of various media chips have emerged. Because different manufacturers have slightly different processes, designs and operation methods, even the same manufacturer Different batches of products will have different product designs and control instructions used in products due to product upgrades and other reasons. Therefore, this kind of situation brings great challenges and problems to manufacturers of back-end equipment production and product application. One is the issue of product compatibility. Back-end equipment manufacturers expect that the storage media controllers used in their products have good compatibility and can be compatible with multiple storage media. In this way, the equipment will have more choices, a...
