ARCHITECTURE
rameter blocks and thirty-one 32K-word blocks. The first
two 4K-word blocks are called boot blocks and are locked
with WP# control. Memory is organized by using a blocked
architecture to allow independent erasure of selected
memory blocks. Any address within a block address range
selects that block for the required READ, WRITE, or ERASE
operation (see Figures 1 and 2).
