Question

COOK Logic Schematic 2. A) Increase the word length of IM x 8 SRAMs to form a IM x 16 SRAM. R/W B) Identify the basic operation functions of a DRAM cell by matching the correct functions for each , diagram shown below b: Writing a 0 into the memory cell d: Writing a l into the memory cell a: Refreshing a stored 1 c: Reading a I from the memory cell iv)

Answer 1

Given 1 m times 8 SRAM increase to form 1m times 16 SRAM From the stated problems we have a static Random Access memory of size 1 m times 8 bit, once re call the basic structure of Ram of The above basic diagram has n - bits of input data is given to the SRAM and n - bit of output data taken from the memory LS is chip selection for enabling the SRAM . There are 2^K address lines are there, each address line or row line have 4 - bit of data . Therefore form the stated problem 1 M times 8 - bit has 1 m address lines and each line have 8 - bit of data, the block diagram shown below, toget 1 m address lines we need 20 - bit address inputs To increase the number of output bits 8 th 16 bits we need two of 1 m times 8 SRAM those are connected in a cascaded format to get
