How is addressing done in DDR memory?

[avantika10]

Hi,
can somebody tell me how addressing is done in DDR memory?

lets say, if i have 14 bits row address and 10 bits column address, and a 4 bank chip, does it mean i have

( 2 ^ 14 ) * (2^10) * 4 number of addressing locations?

Also, if my data bus width (dq) is 16 bits wide, does each address location stores 16 bits of data?

Hi avantika10,

Your thinking is right.
