Address input pins.
A0 to A19 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)
BYTE mode (2M-word by 8-bit)
(The least significant bit (A−1) is combined to O15.)
Data output pins.
O0 to O7, O8 to O14 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)
(The most significant bit (O15) combined to A−1.)
BYTE mode (2M-word by 8-bit)
O15, A−1 are used differently in the WORD mode and the BYTE mode.
WORD mode (1M-word by 16-bit)

Chip activating signal.
When the OE is active, output states are following.
High level : High-Z
Low level : Data out
Output enable signal. The active level of OE is mask option. The active level of OE
Supply voltage
Ground
Not internally connected. (The signal can be connected.)
The pin for switching WORD mode and BYTE mode.
High level : WORD mode (1M-word by 16-bit)
Low level : BYTE mode (2M-word by 8-bit)
A0 to A19 are used as 20 bits address signals.
A0 to A19 are used as the upper 20 bits of total 21 bits of address signal.
The lower 15 bits of 16 bits data outputs to O0 to O14.
8 bits data outputs to O0 to O7 and also O8 to O14 are high impedance.
The most significant output data bus (O15).
The least significant address bus (A−1).
