Embodiment Construction

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

[0082] Figure 1A It is a host system and a memory storage device according to an exemplary embodiment.

[0083] Please refer to Figure 1A , the host system 1000 generally includes a computer 1100 and an input / output (input / output, hereinafter referred to as I / O) device 1106 . The computer 1100 includes a microprocessor 1102 , a random access memory (random access memory, RAM for short) 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 devices shown are not lim...

Abstract

The invention provides a signal processing method, a connector and a memory memorizing device. The signal processing method is applied to the connector which does not comprise a quartz oscillator. The signal processing method comprises receiving a first signal string from a host system; tracking the transmission frequency of the first signal string and obtaining frequency offset of the first signal string relative to the transmission frequency; judging whether the first signal string is performed spread spectrum operation or not according to the frequency offset to generate a judgment result; generating a second signal string according to the judgment result and the transmission frequency. According to the signal processing method, the spread spectrum operation can be processed under the condition that the quartz oscillator is not arranged.

Description

technical field [0001] The present invention relates to a signal processing method, and in particular to a signal processing method of a connector, a connector and a memory storage device. Background technique [0002] Digital cameras, mobile phones, and MP3 players have grown rapidly in recent years, making consumers' demand for storage media also increase rapidly. Since the rewritable non-volatile memory module (for example, flash memory) has the characteristics of data non-volatility, power saving, small size, and no mechanical structure, it is very suitable for being built into various portable multimedia devices listed above. device. [0003] Generally, the rewritable non-volatile memory module is electrically connected to a host system through a connector. In some communication standards, the signal string transmitted between the connector and the host system may undergo spread spectrum clock (hereinafter referred to as SSC) operation, that is, the frequency of the s...
