Memory device

Abstract

The invention relates to a storage device, and its main structure comprises a connector, at least a dynamic memory body and a controller, where the connector is internally equipped with a connecting interface and one end of the controller can connect with the connecting interface and the other end of the controller connects with the dynamic memory body, and the connector and the connecting interface can be selectively fixed and inserted in the USB mating socket, USB connecting port or memory card connecting port of a host computer, and the dynamic memory body can be used to store a startup data or a preset fast read file which is read and used by a CPU as the computer is started, and by the property of high operation speed of the dynamic memory body, it can save startup time of the computer and assure executing validity of ReadyBoost function.

Description

technical field [0001] The present invention relates to a storage device, in particular to a fixed dynamic storage device, which can not only save the booting time of a computer, but also ensure the service life of the storage device. Background technique [0002] A general computer host 10, as shown in FIG. 1, mainly includes a central processing unit (CPU) 13 fixed on a computer motherboard 11, and the CPU 13 can be electrically connected to a system storage 15 and a hard disk (HD) respectively. 16. A physical USB port (connection base) 17 and a USB Pin Header 19 . The physical USB port 17 is directly fixed on the motherboard 11, and the USB pin header 19 can be connected to a USB connector 18 through a USB cable 185, and the USB connector 18 can be optionally fixed on the computer shell appropriate location, such as the front panel of a computer case. Furthermore, an external storage device (External Memory Device) 175 , such as a flash drive or a memory card, can optio...

AI Technical Summary

Problems solved by technology

[0007] 1. The external storage device is generally made of a flash memory (Flash Memory). The operation speed of the flash memory is still much lower than that of a dynamic memory device, and the flash memory has a limit on the number of erasable and writable times and a service life problem.

[0008] 2. When starting up the computer, it is necessary to search the hard disk for booting data or system operating programs, and the waiting time for starting up is very wasteful.

[0009] 3. Every time an external storage device is plugged into a different computer host, or the same computer host uses a different external storage device, it is necessary to reset a new ReadyBoost.sfcache file, which will increase the trouble and waste of time when setting the file

[0010] 4. The storage capacity of the external storage device is often changed due to the storage of other files, and the ReadyBoost.sfcache file is relatively unable to have a fixed or sufficient storage capacity, so the effectiveness of the SuperFetch function or the ReadyBoost function cannot be guaranteed.
