Consider the SRAM binary cell
above and answer the following: Input
Outpul
Read/Write
(a) If Select%3D0, what can you say about the values of S and R? In what sense is the cell "disabled" in this
mode? Explain.
(b) If Select=1, what can you say about the values of S and R? In what sense is the cell "enabled" in this
mode? Explain.
(c) Suppose that Select=D1 and Read/Write3D0. Under these conditions, what can you say about the values of S
and R? Can the latch state be affected by the value of Input, and, if so, why and how? Under these
conditions, can the value of Output be affected by the value of Input, and, if so, why and how?
(d) Suppose that Select=1 and Read/Write=D1. Under these conditions, what can you say about the values of S
and R? Can the latch state be affected by the value of Input, and, if so, why and how? Under these
conditions, can the value of Output be affected by the value of Input, and, if so, why and how?
(e) Based on your above results, does the binary cell exhibit the expected functionality for a memory
element? Explain.
