2k*4 bits RAM memory chips to design a 2K*8 bits main memory module

2k 4 bits RAM memory chips to design a 2K 8 bits main memory module How many 2K 4 bits memory chips should be ysed, 1. Answer. Memory capacity 2K B bits 224 bits RAM chip capacity 2K 4 bits-22"bits So, number of RAM chips required-224/ 2 - 2 2. How many Address lines and data lines are there in memory system repectively. Answer. Number of possible Address 2- 11 So, number of Address line 11 Number of Data line-4 OE Decoder, 4 to 16 MERQ TANSOI A0-A15 Addréss bus AO-A10 ) A0-A11 A11 AND CPU AND zk 4 2k*4 RAM RAM Contral Bus Data bus (DO-D3) Diagram of Connection CPU ,Memory Address bus,Data bus Control Bus

2k 4 bits RAM memory chips to design a 2K 8 bits main memory module How many 2K 4 bits menmory chips should be used 1. Answer.
