(7) All address write (Fig.13)
With this command, the input 16 bits data is written simultaneously to all of the addresses (64 words). Rather than
writing one word at a time, in succession, data is written all at one time, enabling a write time of t
E / W

Fig.13 Write all address cycle timing. (WRAL)
(8) Write disable (Fig.14)
When the power supply is turned on, the IC enters the write disable status. Similarly, when the write disable command
is issued, the IC enters the same status. When in this status, all write commands are ignored, but read commands
may be executed.
In the write enable status, writing begins even if a write command is entered accidentally. To prevent errors of this type,
we recommend executing a write disable command after writing has been completed.
