Embodiment Construction

[0019] FIG. 1 is a basic structural diagram of a flash memory storage device, and the interface between the flash memory and a host, for example, may adopt a USB interface 2.0 protocol. The interface controller is connected to the flash memory controller and the interface, and at the same time performs signal interaction and data transmission between the host interface and the local on-chip flash memory controller. The flash memory array controller can generally be solidified in a chip. The main function of this chip is to analyze the host command according to the feedback signal of the flash memory chip array, generate a command signal queue, and control the target flash memory chip that needs to be operated. It also includes the destination flash memory chip array for storing user data and controller operation, and different designs contain different numbers of flash memories.

[0020] The flash memory controller proposed by the present invention can control a flash memory a...

Abstract

The present invention discloses a flash storage controller. Said flash storage controller includes the following several portions: instruction resolver, transmission controller and several on-chip flash storage control units. Said invention also provides the concrete function and action of above-mentioned every portion, and also provides the working principle of said flash storage controller and its concrete operation method. The flash memory made up by adopting the invented flash storage controller can greatly raise read / write speed.

Description

technical field [0001] The present invention relates to a flash memory controller. Specifically, the present invention relates to a multi-channel parallel flash memory controller with multiple flash memory chips attached thereto. Meanwhile, the present invention also relates to a control chip of a flash memory array. Background technique [0002] At present, with the widespread use of semiconductor medium storage devices, various storage devices and various storage media appear. Among them, the most widely used portable storage device is the U disk. The storage medium it uses is mainly Nand Flash (Nand Flash) in Flash (flash chip). It takes a certain amount of time during the operation process. With the continuous development of various software, users have more and more requirements for the amount of data to be stored, and the capacity of the flash memory storage device has also increased. The waiting time of the flash memory during operation also increases with the amount...
