Double Late Write
Double Late Write means that Data In is required on the third rising edge of clock. Double Late Write is used to implement Pipeline
mode NBT SRAMs.
Byte Write Control
The Byte Write Enable inputs (Bx) determine which bytes will be written. Any combination of Byte Write Enable control pins,
including all or none, may be activated. A Write Cycle with no Byte Write inputs active is a write abort cycle.
