BWb controls DQb. Data I/O are high impedance if either
of these inputs are LOW, conditioned by BWE being LOW.

Input-
Write Enable: This active LOW input gates byte Write
Synchronous operations and must meet the set-up and hold times
around the rising edge of CLK.
Input-
Global Write: This active LOW input allows a full 18-bit
Synchronous Write to occur independent of the BWE and WEn lines and
must meet the set-up and hold times around the rising
edge of CLK.

CLK
Input-
Clock: This signal registers the addresses, data, chip
Synchronous enables, Write control and burst control inputs on its rising
edge. All synchronous inputs must meet set-up and hold
times around the clock’s rising edge.
