Flash module organization

The memory organization is based on a main memory block containing 32 pages of 1 Kbyte
(for low-density devices), 128 pages of 1 Kbyte (for medium-density devices), 128 pages of
2 Kbyte (for connectivity line devices) or 256 pages of 2 Kbyte (for high-density devices),
and an information block as shown in
6/31
Main memory block:
4 Kbits × 64 bits for low-density devices
16 Kbits × 64 bits for medium-density devices
64 Kbits × 64 bits for high-density devices
32 Kbits × 64 bits for connectivity line devices
Information block:
2306 × 64 bits for connectivity line devices
258 × 64 bits for other devices
