Problems solved by technology

The existing flash memory storage device can only read one byte at a time, and transfer the data to the host after accumulating up to one sector (that is, 512 bytes), so it is different from the read / write of the hard disk drive. Compared with the speed of input, the storage device of flash memory really needs to find a faster way in terms of access speed

Embodiment Construction

[0011] See figure 1 , figure 1 It is a schematic diagram of the multi-channel flash memory access data method of the present invention. Such as figure 1 As shown, the data access method of the present invention is at first such as 8 rows of flash memory 16a~16c, 17a~17c, 18a~18c, 19a~19c, 20a~20c, 21a~21c, 22a~22c, 23a~23c, flash memory control Eight predetermined communication channels are established between the devices 14a, 14b. Each communication channel is still the same as the prior art, and each channel can only access one byte of data at a time. However, the number of communication channels can be from 2 to 512, and is not limited as figure 1 8 shown. The number of flash memory controllers 14a, 14b is not limited too much, the more controllers, the faster each communication channel can access data.

[0012] To put it simply, the multi-channel flash memory access data method of the present invention is mainly used in flash memory storage devices, and in order to r...

Abstract

The invention discloses a multi-channel flash memory access data method. First, a predetermined number of communication channels are established between a plurality of flash memories and flash memory controllers. Since each communication channel can transmit a single byte of data, if the predetermined number of bytes of data are transmitted from a predetermined number of communication channels synchronously, as long as the accumulation reaches the defined value of the sector, it can be as The hard disk drive transmits data to the host side.

Description

technical field [0001] The invention relates to a flash memory access data method, in particular to a multi-channel flash memory access data method. Background technique [0002] The large-capacity storage devices used in general computers are all hard disk drives, and along with the technology of hard disk drives is maturing day by day, no matter capacity, price have all reached a satisfactory level. However, the read head of the hard disk drive still has physical contact with the magnetic disk that actually stores the data when accessing data, which makes the magnetic disk easy to damage and the data stored in the hard disk drive to be easily lost. In addition, the hard disk must use a high-speed rotating motor to drive the magnetic platter, so power consumption has always been a difficult problem to solve. This is even more of a problem for portable devices (such as notebook computers) with stricter power consumption requirements. [0003] In order to solve the above pr...
