Embodiment Construction

[0081] Generally speaking, a memory (also called a memory storage system) includes a rewritable non-volatile memory module and a controller (also called a control circuit). Typically memory is used with a host system so that the host system can write data to and read data from the memory.

[0082] Figure 1A It is a schematic diagram of a host system and a memory according to an embodiment.

[0083] Please refer to Figure 1A , the host system 1000 generally includes a computer 1100 and an input / output (I / O) device 1106 . The computer 1100 includes a microprocessor 1102 , a random access memory (RAM) 1104 , a system bus 1108 and a data transmission interface 1110 . The input / output device 1106 includes such as Figure 1B mouse 1202, keyboard 1204, monitor 1206 and printer 1208. It is important to understand that Figure 1B The illustrated devices are not limited to the I / O device 1106, which may further include other devices.

Abstract

The invention provides a system operating method, a memory controller and a memory. The system operating method is used for controlling a rewritable nonvolatile memory module with a plurality of entity blocks. The system operating method comprises the following steps: receiving a first signal from a host computer system through a host computer interface; judging whether the system settings of the host computer interface are needed to be changed or not; if the system settings of the host computer interface are needed to be changed, reading a system parameter from the entity blocks and changing the system settings according to the system parameter; transmitting a secondary signal to the host computer system so as to build an aggregate identification between the rewritable nonvolatile memory module and the host computer system. Thus, transmission settings between the host computer system and the rewritable nonvolatile memory module are more flexible.

Description

technical field [0001] The present invention relates to a system operation method, and in particular to a system operation method for a rewritable non-volatile memory module and a memory controller and memory using the method. Background technique [0002] The rapid growth of digital cameras, mobile phones and MP3 players in recent years has led to a rapid increase in consumer demand for storage media. Since the rewritable non-volatile memory module (for example, flash memory) has the characteristics of non-volatility of data, power saving, small size, and no mechanical structure, it is very suitable for being built in various portable devices such as the above examples. in multimedia devices. [0003] Generally, the rewritable non-volatile memory module is electrically connected to a host system through a transmission interface. When the rewritable non-volatile memory module is electrically connected to the host system, the default system setting of the transmission inter...
