... KWords and seven Main Blocks of 64 KBytes or 32 KWords. The M29W400T has the Boot Block at the top of the memory address space and the M29W400B locates the Boot Block starting at the bottom. The memory maps are showed in Figure 3. Each block can be erased separately, any com- bination of blocks can be specified for multi-block erase or the entire chip may be erased ...

... M29W400T, M29W400B Command Interface Instructions, made up of commands written in cy- cles, can be given to the Program/Erase Controller through a Command Interface (C.I.). For added data protection, program or erase execution starts after cycles. The first, second, fourth and fifth cycles are used to input Coded cycles to the C.I. ...
