Device Address (A0, A1, A2)
Eight devices can be wired for one common data bus line as maximum. Device address pins are used to distinguish
each device and device address pins should be connected to V CC or V SS . When device address code provided from SDA
pin matches corresponding hard-wired device address pins A0 to A2, that one device can be activated.

Write Protect (WP)
When the Write Protect pin (WP) is high, the write protection feature is enabled and operates as shown in the following
table. Also, acknowledgment "0" is outputted after inputting device address and memory address. After inputting write
data, acknowledgment "1"(NO ACK) is outputted.
When the WP is low, write operation for all memory arrays are allowed. The read operation is always activated
irrespective of the WP pin status.
