A computer uses RAM chips of 1024×1 capacity. How many chips are needed & how should their address lines be connected to provide a memory capacity of 2048 bytes?? Ans : RAM chip capacity is 1024×1 Well this defines columns & rows i.e 1024 columns × 1 row = Therefore total memory capacity = 1024 ×1 = 1024 bits. We know that 1 byte= 8 bits Therefore , 2048 bytes= 2048 × 8 bits Applying unitary method If 1024 bits = 1 chip 1 bit. = 1/1024 chip 2048 × 8 bits= (2048×8)/1024 = 16 chips Address lines: 2048 = 2ⁿ ( n= no. of address lines) n= 11 as 1 chip= 1024 bits Address lines for 1 chip : 1024= 2¹⁰ therefore 11 address lines are required for 16 chips where 10 address lines are common to ...
