i am trying to understand memories , i may be completely wrong also.
please help me with your comments.
we use row and column decoders in memories.
if i have 128 * 128 bit memory ( to maintain aspect ratio)
i will have 14 bit address line.
as per my understanding i will give 7 bit of address for row decoders and remaining 7 bits for column decoders.
now my row decoder will enable word lines of a particular row and all 128 bit cells will get activated in that row.
i am confused how will column decoder work here?
do we activate a complete row , take all data from all bitlines and then choose right one using column decoder?
or
do we first activate a row ,then further activate columns and read only that particular bit cell...
i suppose option 2 should be correct , but i could not find any data on this
please help
