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
.
How many address lines are required for 8kB?
It is an 8kB and his question uses a 32kB RAM. Both simply have 8k of addressable words and therefore need
13 address lines
.
How many address lines are needed to address each?
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
.
How many locations can be addressed by?
Answer: Aroun 16 Kilo Bytes of memory locations can be addressed. You can calculate the number of memory locations by using this formula: No. of Memory locations
= 2^n
, where n = number of address lines.
What are CPU address lines?
The number of lines (wires) in the address bus
determines the maximum amount of RAM that can be directly accessed by the CPU
as each line carries one bit of the address. In 1981, the IBM PC had a limit of one megabyte of RAM because its address bus had 20 lines, and 20 bits represents the number 1,048,576 in binary.
How many address lines does 256 * 4 memory have?
How many data lines does 256*4 have? Explanation: There are
four data
lines in the memory and these different organisations of memory and these different organisations of memory are apparent when upgrading memory and it also determines how many chips are needed.
How many locations are addressed using 18 address bits *?
How many memory locations are addressed using 18 address bits? Explanation: For n address bits, the memory location will consist of 2
n
bits. Using 18 address bits, 2
18
=
262,144 (= 256 K)
words are addressed.
How many address lines are needed for 2 MB?
Answer: It requires
21 address lines
to address two megabytes of memory.
How many locations of memory can you address with 12 bit memory address?
Each memory location is one byte, while the address is 12-bit, with the capability to address up to
4096 locations
.
What is a 32-bit address?
A 32-bit address is
the address of a single byte
. Thirty-two wires of the bus contain an address (there are many more bus wires for timing and control). Sometimes people talk about addresses like 0x2000, which looks like a pattern of just 16 bits. But this is just an abbreviation for the full 32-bit address.
What are the address lines?
- Address Line 1 is generally for the civic number and street name (street address).
- Address Line 2 is for the apartment, suite, unit number, or other address designation that is not part of the physical address.
- Address Line 3 is typically for the city, state, and zip code.
Which is the fastest memory?
- Fastest memory is cache memory.
- Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.
How many address lines are there in 8086?
The 8086 uses
20
-line address bus. It has a 16-line data bus. The 20 lines of the address bus operate in multiplexed mode.
How many address lines are there in 8085?
The microprocessor 8085 has
16 bit
address lines from A15-A8 and AD7-AD0. These lines are used to transfer 16 bit address of memory as well as 8-bit address of I/O ports.
How many address lines are required for 1MB memory?
“
20”
address lines or address bus are required to span “1MB” memory space.
