Block Structure

Figure 24.4 shows the 160-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 160-kbyte user MAT is divided into one 64-kbyte block, 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.
