Consider a DRAM chip of capacity 256 KB and each memory location contains 8 bits. The memory chip is organized in matrix form with equal number of rows and column for each memory location of 8 bits. This DRAM chip has a refresh interval of 64 ms, memory bus runs at 200 MHz, and the refresh cycle takes 4 clock cycle. a) Time required to refresh the DRAM chip. b) What is the minimum size of the refresh counter?
