Abstract

The embodiment of the invention provides an operation frequency adjusting method and device, and the method is executed by a processing unit of a device end, and comprises the steps: collecting an interface activity parameter; selecting one from a plurality of frequencies according to the interface activity parameter; and driving a clock generator to output a clock signal of the selected frequency, so that a host access interface and / or a flash memory access interface operate / operates at the corresponding operation frequency.

Description

technical field [0001] The invention relates to a flash storage device, in particular to a method and device for adjusting operating frequency. Background technique [0002] Flash storage devices are generally classified into NOR flash storage devices and NAND flash storage devices. The NOR flash storage device is a random access device. The host (Host) can provide any address to access the NOR flash storage device on the address pin, and obtain the data stored at the address from the data pin of the NOR flash storage device in time. on the data. In contrast, NAND flash storage devices do not have random access, but sequential access. The NAND flash storage device cannot access any random address like the NOR flash storage device. Instead, the host side needs to write the value of the sequence of bytes (Bytes) into the NAND flash storage device to define the request command (Command). Type (eg, read, write, erase, etc.), and the address used on this command. The address ...
