Abstract

The invention discloses a controller used for memories and a method for using the controller; with the invention, a logical function register is adjusted according to a received first signal so as to bind with a logical function corresponding to the memory type; a level mode of an input-output port of the controller and a drive load capacity are adjusted according to a received second signal; therefore, control of various types of memories can be supported by a same controller. In addition, through automatic detection of the operation sequence of the controller, the processing efficiency and the flexibility are improved.

Description

technical field [0001] The invention relates to the technical field of storage control, in particular to a controller for storage and a method for applying the controller. Background technique [0002] As embedded products are more and more widely used in consumer electronics, industry, security and other fields, people need a large amount of dynamic random access memory (DRAM), which is used to dynamically store data, run system and application-related codes and data. [0003] For example, the dynamic memory DDR2SDRAM currently used on the market. Since the ddr2 memory is a high-speed storage device, its controller needs to consider the signal problem, and most of the general controllers are done on the timing of the hardware, that is to say, the designer of the controller will In the protocol circuit, according to the JEDEC (Joint Electron Device Engineering Council) standard, an operation sequence that supports the standard is given, and some controller designers use a h...
