PROBLEM TO BE SOLVED: To provide a flash memory device configured to allow a cache read operation of preceding page data.SOLUTION: The flash memory device includes an array of memory cells for storing data pages, one or more buffers for retrieving the data pages, and a logic mechanism that, responsive to a plurality of commands, transfers the data pages between the buffers and a host. Each command subsequent to a first command instructs retrieval of a data page whose address either precedes or exceeds by more than 1, the address of the data page retrieved by the immediately preceding command, and at least one command does not explicitly specify the address of its retrieved data page. Another similar flash memory device uses two buffers to implement cache reads of data pages whose addresses are specified arbitrarily in the commands subsequent to the first command. |
