Device operations

This section provides details of the device operations.

6.1

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).

6.1.1

Random read

Each time the read command is issued, the first read is random read.

6.1.2

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 tWHBH (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.
