Cache read
The cache read operation improves the read throughput by reading data using the cache
register. As soon as the user starts to read one page, the device automatically loads the
next page into the cache register.
A Read Page command, as defined in
first Read Cache command in a read cache sequence. Once the Read Page command
execution is terminated, the Cache Read command can be issued as follows:
1.
2.
The two commands can be used interchangeably, in any order. When there are no more
pages are to be read, the final page is copied into the cache register by issuing the Exit
Cache Read command. A Read Cache command must not be issued after the last page of
the device is read. Data output only starts after issuing the 31h command for the first time.
