How many address lines are needed to address each memory location in a 2048 x 4 memory chip?
a) 10
b) 12
c) 8
d) 11
e) None of these
Answer »Answer: (d)
Notes: 11 address lines are needed to address each machine location in a 2048 X 4 memory chip.
It means a memory of 2048 words, where each word is 4 bits. So to address 2048 (or 2K, where K means 2^10 or 1024), you need 11 bits, so 11 address lines. To express in very easy terms, without any bus-multiplexing, the number of bits required to address memory is the number of lines (address or data) required to access that memory.
