Read memory array
At power-up the device defaults to read mode. To enter read mode from another mode, the
read command must be issued (see Table 9: Commands).
Random read
Each time the read command is issued, the first read is random read.
Page read
After the first random read access, the page data (2112 bytes or 1056 words) is transferred
to the page buffer in a time of t_WHBH (see Table 28). Once the transfer is complete, the
Ready/Busy signal goes High. The data can then be read sequentially (from selected
column address to last column address) by pulsing the Read Enable signal.
The devices can output random data in a page, instead of consecutive sequential data, by
issuing a Random Data Output command. The Random Data Output command can be used
to skip some data during a sequential data output.
The sequential operation can be resumed by changing the column address of the next data
to be output, to the address which follows the Random Data Output command. The Random
Data Output command can be issued as many times as required within a page.
The Random Data Output command is not accepted during cache read operations.
