Non-volatile memory set-value loading method and memory device

Abstract

In early stage for fabricating memory device, setting value of specific compatible memory is loaded to prearranged preload area in one of non-volatile memory block. Thus, information of each parameterof the non-volatile memory type is preloaded. When preparing the memory, the method loads the information in preload area to RAM of the memory device in order to save space by using well-known ROM torecord memory type. When activating the memory device, the method uses loads the setting value of non-volatile memory in preload area to RAM of the memory device so as to accomplish flow of preparingthe memory or updating firmware.

Description

technical field [0001] A non-volatile memory setting value loading method and its memory device, especially when a memory device is manufactured, the setting value of a specific non-volatile memory is first loaded to a preset preload area, and the setting is loaded when activated value into the random access memory of the memory device, completing the preparation of the memory device. Background technique [0002] When a flash memory module manufacturer manufactures a flash memory (Flash memory)-related memory device, it needs to comply with various memory types and specifications defined by the manufacturer. Designing a memory device often needs to be compatible with multiple types or specifications at the same time. In order to overcome the differences in memory types or specifications produced by manufacturers, the most commonly used method is to control the firmware part in the device, and directly load all the compatible flash memory type information during production, ...

Problems solved by technology

In order to overcome the differences in memory types or specifications produced by manufacturers, the most commonly used method is to control the firmware part in the device, and directly load all the compatible flash memory type information during production, such as making the firmware part For read-only memory (ROM), one process (such as masking, etching, etc.) includes all the required information, and the production often requires a larger memory size, and the process often takes one or two months. During this period, if any update or modification is made by the memory manufacturer, the firmware needs to be redesigned, which not only consumes time and cost, but also causes inventory problems.
