Abstract

See full text

A WC resource usage is compared with an auto flush (AU) threshold Caf that is smaller than an upper limit Clmt, and when the WC resource usage exceeds the AF threshold Caf, the organizing state of a NAND memory 10 is checked. When the organizing of the NAND memory 10 has proceeded sufficiently, data is flushed from a write cache (WC) 21 to the NAND memory 10 early, so that the response to the subsequent write command is improved.
