Problem 5 (24 points): A 32-word static RAM is to be arranged in a 'square' (16x16) with aspect ratio of as close to 1 as possible. Word length is 2 bits, and address bits are labelled AAsA2AiAo. Draw the memory structure showing various components as blocks. Properly a. label rows and columns. (You do not have to draw all the columns and rows, ju enough to make the diagram clear. Do not draw bit lines for this part.) b. Determine which address bits are for the row-decoder. c. Determine which address bits for the column decoder. d. Determine the number of sense amplifiers needed. e. Determine the number of pre-charge circuits needed f. Determine the number of memory cells needed. g. Draw sample circuits of i. Sense amplifier. ii. Pre-charge circuit. ii 6T static RAM cell
