Question

explain and show the organization of 64k*8 memory module using 16k*1 static memory chips(show CS,R/W,control lines,Address and data bus)

Answer 1

Answer:

Memory capacity is 2 dimension. Rows and Columns. So, here 64K refers to Rows(Word) and 8 refers to Column (numbers of bits per Word).

In order to represent 64K x 8 with 16K x 1, we will require 8 columns and 4 rows each of 16K x 1 memory chip. Each chip has a control input CS. When this input is set to 1, it enables that chip to accept that data input or to place the data on its output line. The address bus is 16 bit wide and the higher order 2 bits are decoded to obtain the four chip select (CS) control signal. Remaining 14 bits are used to access specific bit locations. R/W inputs of all chips are tied together to provide a provide a common Read/Write control
