DEVICE OPERATION
Read Mode
Read mode is set when the "00h" and “30h” commands are issued to the Command register. Between the two
commands, a start address for the Read mode needs to be issued. Refer to the figures below for the sequence and
the block diagram (Refer to the detailed timing chart.).

A data transfer operation from the cell array to the register
starts on the rising edge of WE in the 30h command input
cycle (after the address information has been latched). The
device will be in the Busy state during this transfer period.
After the transfer period, the device returns to Ready state.
Serial data can be output synchronously with the RE clock
from the start address designated in the address input cycle.

Cell array
During the serial data output from the register the column
address can be changed by inputting a new column address
using the 05h and E0h commands. The data is read out in serial
starting at the new column address. Random Column Address
Change operation can be done multiple times within the same
page.
