Embodiment Construction

[0017] Certain terms are used throughout the specification and claims to refer to particular elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same element. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open-ended term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that the first device is coupled to the second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

A solid state disk drive and an operation frequency control method are provided. The solid state disk drive comprises a memory device and a controller, wherein, the memory device comprises a plurality of memory units for storing data bits; the controller is coupled to the memory device, the memory device can be accessed and the workload of the memory device can be estimated according to the clock signal, and the frequency of the clock signal can be adjusted according to the estimated workload. The solid state disk drive and the operation frequency control method can control the operation frequency of an SSD driver according to the system workload, thereby decreasing the system power consumption and improving the system performance.

Description

technical field [0001] The present invention relates to a solid-state hard disk drive, and in particular to a solid-state hard disk drive and an operating frequency control method. Background technique [0002] Computer systems store data in different types of storage media and devices. The storage medium and device can be regarded as nonvolatile, and can store data continuously even when the power is turned off. One example of a non-volatile storage device is the hard disk of a computer system. The storage device may also include a NAND (hereinafter referred to as NAND) flash memory and a solid state disk (hereinafter referred to as SSD). The storage medium may include actual disks or platters accessed by the storage device. An operating system (operating system, hereinafter referred to as OS) may be required to perform some actions, for example, a processor reads and writes a specific location in a storage medium. [0003] Since the non-volatile flash memory has been w...
