Block Structure

Figure 24.4 shows the 96-kbyte block structure. The heavy-line frames indicate the erase blocks.
The thin-line frames indicate the programming units and the values inside the frames indicates the
addresses. The 96-kbyte user MAT is divided into two 32-kbyte blocks and eight 4-kbyte blocks.
The user MAT can be erased in these block units. Programming is done in 128-byte units starting
from where the lower address is H'00 or H'80.
