Question

Computer Science
We want to use a single ROM as a lookup table that can perform two
bitwise operations, XOR and NAND. There are two operands with each
operand being 4 bits (X3X2X1X, and Y3Y2Y1Y0), and a selector (S) for
the operation chosen.
(a) How many address lines (the least amount possible) are needed for
the ROM?
(b) How many output lines (the least amount possible) are needed for
the ROM?
(c) If we use a 1024x10 ROM, how many columns will be unused?
(d) If we use a 1024x10 ROM, how many rows will be unused?

True/False During the 'READ' of the SRAM structure studied in the class, the bit and bit_bar are both precharged to a high, and then the word line is turned high. This will always result in one of the bit or the bit_bar lines to start tending to go low, while the other remains at the precharged levels.
