How many address lines are used in 4k memory
WebSep 10, 2015 · If your machine always loaded say 64B cache lines, and your RAM was set up to deliver 64B bursts from a requested address, you'd only need 10 address lines to cover the same 64k of memory. The CPU would sort out which byte the load actually wanted internally, without needing to put the . (Or with 16 address lines, 2^16 * 64B addressability). WebHow many address lines would we need for a 1 ... • 4K words of word-addressable main memory. • 16-bit data words. • 16-bit instructions, 4 for the opcode and 12 for the address. • A 16-bit arithmetic logic unit (ALU). ... • Memory address register, MAR, a 12-bit register that

WebJun 30, 2024 · Data pins: Since each memory location stores eight bits, there are eight data lines D0-D7 connected to the memory chip. Address pins: The number of address pins depends on the size of the memory. In this case, a memory of size 1 kB x 8 will have 2 10 different memory locations. Hence, it will have ten address lines A0 to A9.

Sorted by: 7. 256x8 = 256 cells that hold 8 bits each, so the total capacity of that chip is 256 bytes (or 2048 bits). 4096/256=16. Share.
WebHow many address lines are needed to select one of the memory chips? 32 MB is 2^5 so 5 address lines are needed to select one of the memory chips. Suppose a system has a byte-addressable memory size of 4GB. How many bits are required for each address? 4GB is 2^2 x 2^30 =232. Thus, 32 bits are required for each address. WebQuestion 1 How many address bits are needed to select all locations in a 256 x S memory? Question 2 Assume a 16Kx8 memory is designed using 4Kx1 RAM chips. How many …
Web11 address lines are needed to address each machine location in a 2048 X 4 memory chip. It means that 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.
