The
MAR is a special register in the sense that each time it is accessed from the outside, memory senses it and
considers the new content of the MAR an address.
It is used to hold data or the memory address that contains either the next place of data or an instruction that is to be used .
memory addres register is used hold data addresses that refer to the data portion of the memory(by umar farooq.pk) memory addres register is used hold data addresses that refer to the data portion of the memory(by umar farooq.pk)
A data register is temporary data being transmitted or shifted in 1s or 0s to or from the byte-organized memory array from the bidirectional data bus. The write operation shifts data into the the byte-organized memory array and the read operation shifts data into the data register.
A register is temporary memory which can store single bit of data....
In other words, MAR holds the memory location of data that needs to be accessed. When reading from memory, data addressed by MAR is fed into the MDR (memory data register) and then used by the CPU. When writing to memory, the CPU writes data from MDR to the memory location whose address is stored in MAR. The Memory Address Register is half of a minimal interface between a microprogram and computer storage. The other half is a memory data register. Far more complex memory interfaces exist, but this is the least that can work.
Register memory are smaller in size than cache memory and registers are faster than cache..Cache memory store the frequently used data from main memory..
holds 16 bit data just fetched from the memory
MAR-memory address register used stored the address of the memory loaction MBR- memory buffer register is the actully data.
yes
this is the memory that hold data temperaly and can be used in future
MAR is memory address register. MDR is memory data register. These are registers part of the control unit (CU) in your cpu.
It is used to hold data or the memory address that contains either the next place of data or an instruction that is to be used .
