Hi All,
I need to connect 32M8 256Mb SDRAM to a processor. The SDRAM has
13 Address Lines for Row Decoding (8K rows) and 10 Address lines for column
decoding (1K columns) and two additional address lines BA0 and BA1. I am
connecting A0-A12 of processor's address bus to A0-12 of SDRAM and A13,A14
of processor to BA0,BA1 of SDRAM (alongwith other signals of read or
write).Is this way of connection true ?.
Also I want to know of any hardware or software technique by which we can
limit the size of 256Mb RAM to 128Mb or 64 Mb.
Regards,
Adeel
