Address inputs (A0-Amax)
Amax is equal to A19 in the M29W160FT/B, and to A20 in the M29W320FT/B.
The Address inputs select the cells in the memory array to access during Bus Read
operations. During Bus Write operations they control the commands sent to the command
interface of the Program/Erase controller.
Data inputs/outputs (DQ0-DQ7)
The Data inputs/outputs output the data stored at the selected address during a Bus Read
operation. During Bus Write operations they represent the commands sent to the command
interface of the Program/Erase controller.
Data inputs/outputs (DQ8-DQ14)
The Data inputs/outputs output the data stored at the selected address during a Bus Read
operation when BYTE is High, V
high impedance. During Bus Write operations the Command Register does not use these
bits. When reading the Status Register these bits should be ignored.

the word on the other addresses, DQ15A–1 High will select the MSB. Throughout the text
consider references to the Data input/output to include this pin when BYTE is High and
references to the Address inputs to include this pin when BYTE is Low except when stated
explicitly otherwise.
Chip Enable (E)
The Chip Enable, E, activates the memory, allowing Bus Read and Bus Write operations to
be performed. When Chip Enable is High, V
Output Enable (G)
The Output Enable, G, controls the Bus Read operation of the memory.
