Embodiment Construction

[0042] Since the hardware architectures of various flash memories are different, in order to be able to manage different types of flash memories, it is necessary to set all flash memories in compatible formats and store these settings in advance. Then, when receiving data access instructions, The correct data access location and method can be found through the query method, and the data access action can be performed between different types of flash memory. The present invention is a set of management methods, systems and controllers for various memories developed by adopting the above concepts. In order to make the content of the present invention clearer, the following specific examples are given as the basis for the actual implementation of the present invention.

[0043] figure 1 It is a block diagram of a management system of various memories according to an embodiment of the present invention. Please refer to figure 1 , the management system 100 of this embodiment inc...

Abstract

The invention provides a method, a system and a controller for managing multiple memorizers. According to hardware frames of the memorizers, the data accessing format of each memorizer is adjusted to ensure that an accessing unit for accessing data in every time is same, and a mapping table is established to record the adjusted data accessing format of each memorizer. When a data accessing instruction sent by a host computer end is received, the data accessing instruct can be executed by inquiring the mapping table. The invention can solve the incompatible problem of the hardware frames and can manage flash memories of different types.

Description

technical field [0001] The present invention relates to a memory management method and system, and in particular to a management method, system and controller of multiple types of memory. Background technique [0002] Electronic products such as digital cameras, cell phone cameras, and MP3 players have grown rapidly in recent years, making consumers' demand for storage media also increase rapidly. Among a wide variety of storage media, flash memory (Flash Memory) is especially suitable for portable devices powered by batteries, such as notebook computers or personal digital assistants, due to its non-volatility, power saving, small size, and no mechanical structure. type products, and as the built-in memory of such portable products. In addition, flash memory is also suitable for use as small storage media such as memory cards or flash drives. Due to the wider application level and larger market scale of flash drives and memory cards, flash memory has become a very popular ...
