3. [Memory Design] Build a 2K*16 bit ROM using any number of lK*8 bit ROMs The block you use to represent 2K* 16 ROM should have a 11-bit wide address input, a chip-select (CS) input, and a 8-bit wide data output. (Hint: A[9:0]: 10-bit address input, CS: a 1-bit chip-select input, Dout[7:0]: 8-bit data output.) 10 A[9:0] 1K X8 8 Dout 7:0 ROM CS 1 Ans: A19:0 49이...

A computer system has a 20-bit address bus and can address an 8-bit wide memory. The memory of this computer system contains 64 Kbytes of ROM and 256 Kbytes of RAM. The ROM and RAM form a contiguous block of memory starting at address 0. What is the maximum number of addressable memory locations can this computer system address? Give your answer in power of 2. Draw a memory map for the computer system. Indicate the starting and ending addresses...

Consider a RAM system of size 64 Kbytes. For each of the following cases show how this RAM can be built. Draw a MEMORY MAP showing which chips are used for which range of addresses. Draw a NEAT drawing (employ the use of drawing aids such as rulers, templates, etc.) showing how the chips are connected to the address decoder and the CPU address, data, and control lines: (a) Use memory chips each having 8K x 8 bits. (b) Use...
