Function
These bits indicate the number of column address lines. The bits are encoded for
SDRAM as follows:
’000’
’001’
’010’
’011’
’1XX’
The bits are encoded for SRAM as follows:
’000’
’001’
’010’
’011’
’100’
’101’
’110’
’111’
These bits indicate the total amount of memory present, that is, two 64MB SDRAM
arrays would result in a value of 128MB in these bits. The bits are encoded as follows:
’000’
’001’
’010’
’011’
’100’
’101’
’110’
’111’
This two bit indicates the number of arrays of DRAM present. This bit set to ’0’ indicates
one array; the bit set to ’1’ indicates two arrays.
8 column address lines (256 words/row)
9 column address lines (512 words/row)
10 column address lines (1K words/row)
