how many unique RAM memory bytes can a CPU access if it has 22 lines/bits on...
Homework Answers
If we consider that the memory is byte addressable i.e. if each byte of the RAM or memory gets a unique address then the number of unique RAM memory bytes that the CPU can access using 22 lines/bits on the address bus is = 222 = 4194304 as we get 222 unique combinations of the address.

Consider 512Kx8bits dynamic RAM chips where the memory access time is 2/3 of the memory cycle time. These chips have an Address Bus, a bi-directional Data Bus, a Read/Write control line and a Chip Select line. (a) Draw the diagram of a memory organization that will contain 4 megabytes, will have a 32-bit bi-directional data bus and will yield one word (32-bits) every access time if words are read from consecutive memory locations (in bursts). Clearly show and explain the...
