SDRAM Calculation of capacity

Calculate the number of addressable locations (don’t think of bit/byte/word for now)
Number of address lines: 11 (A0-A10)
Number of banks : 2 (BA0-BA1)
Max number of rows = 11 (i.e., no. of address lines)
Max number of columns = 11 (i.e., no. of address lines)
Total locations in a bank = 211 x 211
Total locations in the chip = (No. of banks) x (Total locations in a bank)
= 22 x 211 x 211
= 224
Organization: x4, x8, x16
Look for the min possible organization, i.e. x4
Max capacity of the chip is 224 x4 = 226 bits
