FLASH MEMORY DEVICE HAVING A FLASH CACHE PORTION AND A METHOD FOR USING THE SAME

摘要

A flash memory device is presented. The device includes a flash memory (110), which has a temporary storage portion (112), a main storage portion (111) and a controller (120). The temporary storage portion (112) is provided for buffering data and addresses. The buffered addresses are indicative of the destination of the buffered data in the main storage portion (111). The controller (120) is configured for selectively accessing the main storage portion (111) or the temporary storage portion (112) or a combination thereof for receiving and/or outputting the data from the memory. The controller (120) is further configured for enabling communication of data between the two portions. Because non-volatile flash memory is used for the temporary storage (112), no other memory components are needed and, in case of an unexpected power failure, the data in the temporary area is not lost.
