Notes
1. Page Size and Length is a function of I/O
organization:
128Mb x 4 organization (CA[9:0], CA11); Page Size
= 1 KByte; Page Length = 2048
64Mb x 8 organization (CA[9:0]); Page Size = 1
KByte; Page Length = 1024
32Mb x 16 organization (CA[9:0]); Page Size = 2
KByte; Page Length = 1024
2. Order of burst access for sequential addressing is
“nibble-based” and therefore different from SDR or
DDR components
