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 Cache Read command in a cache read 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 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.
