Abstract: The invention presents a multi-type flash memory with simulating system and a method thereof. Meanwhile the method includes the steps of a) providing a simulating circuit data for the multi-type flash memory; b) transforming the simulating circuit data into a programmable circuit device; c) connecting a flash memory access interface of the multi-type flash memory with a first host system; d) connecting a large-scale access interface of the multi-type flash memory with a second host system; e) transmitting data signals between a buffer register of the multi-type flash memory and the first/second host systems via the flash memory access interface/the large-scale access interface; and f) transmitting control signal between the buffer register and the first/second host systems via the programmable circuit device and the flash memory access interface/the large-scale access interface, thereby incorporating a simulating system into the multi-type flash memory conveniently.

Abstract: The invention presents a flash memory with a generalized interface for facilitating to develop multi-type flash memories and a method thereof. Meanwhile the generalized flash memory includes a physical memory for storing data; a logical controller connected with the physical memory for providing an identify function of the physical memory and communicating with an external system in an unified format; and a buffer register connected with the logical controller, wherein the logical controller and the buffer register map the physical memory to an entire continuous memory space, thereby facilitating to develop multi-type flash memories.

Abstract: A flash storage device for transferring data to and from a host. The flash storage uses a controller to data transfer in the flash storage device, a buffer to temporarily store data for transfer between the host and the flash storage device, a first table for maintaining storage information relating to the flash storage; and a second table for maintaining information relating to the association of virtual sectors to the logical sectors, wherein the controller transfers data between the host and the flash storage and updates the first table and the second table to reflect the transfer of the data. The first table and the second table contain include addressing and status information for a more efficient and improved data transfer.

Abstract: A data management for a flash memory device is disclosed. The device includes a screen virtual sector table and a virtual unit versus physical unit table (V2P table) for each block. With the auxiliary of the screen virtual sector table and v2p table, the data programming into the target block of the flash memory is in accordance with the data receiving order, which is from lower page number to higher page number in case the target block is free. The data can be written into the target block contains data already through one or two temporal block(s). The conventional LBA data transfer protocol can still be applied to the flash memory device of this invention.
