Webb8 feb. 2009 · Shared memory is of size 16KB. It is divided into 16 banks each having 1KB. In the shared memory successive 32 bit words belong to successive banks (e.g., if we access the 18 th word it belongs to 18%16 = 2nd bank ). Each bank has a bandwidth of 32 bits per clock cycle i.e., at any clock cycle a bank can give only 32 bits i.e., a word.
