<p><P>PROBLEM TO BE SOLVED: To provide a flash memory data storage apparatus that improves a data transfer rate between a flash memory and an external system. <P>SOLUTION: In the flash memory data storage apparatus, a multistage flash input buffer unit is incorporated in which data bus width is gradually extended and the period of a control clock is gradually made longer. The flash memory data storage apparatus renders its embedded flash memory to be accessed with 128-bit data in parallel in a period of 80 ns, while communicating with an external system for 16-bit data in parallel during a period of 20 ns. Thus, the flash memory data storage apparatus of the present invention improves the data transfer rate between the flash memory and a buffer memory, resulting in remarkable advancement of the data transfer rate between the flash memory and the external system. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
