8.33 INFORMATION ROW ERASE OPERATION (IRER, 64h)

Information Row Erase (IRER) instruction erases the data in the Information Row x (x: 0~3) array. Prior to the

operation, the Write Enable Latch (WEL) must be set via a Write Enable (WREN) instruction. The WEL bit is

automatically reset after the completion of the operation.

The sequence of IRER operation: Pull CE# low to select the device  Send IRER instruction code  Send

three address bytes  Pull CE# high. CE# should remain low during the entire instruction sequence. Once CE#

is pulled high, Erase operation will begin immediately. The internal control logic automatically handles the erase

voltage and timing. Refer to Figure 8.49 for IRER Sequence.
