What function does memory interleaving perform?
A.
It allows Static RAM (SRAM) to stores data without requiring data-refreshing operations.
B.
It allows Dynamic RAM (DRAM) to detect and repair memory errors on the fly.
C.
It allows one bank of Synchronous DRAM (SDRAM) to be accessed while the other bank is completing an operation.
D.
It allows Rambus to operate at much higher speeds than conventional 64-bit memory buses
Explanation:
Server memory can be logically divided into multiple sections to allow the processor to access data held in memory from multiple sources. Typical interleaving schemes divide the memory into two banks of RAM, allowing data in one bank of memory to be accessed while the data in the other bank refreshes.Incorrect Answers:
A: Static RAM (SRAM) stores data in IC transistors for as long as power to the memory chips is not interrupted. It does not require periodic data-refreshing.
B: Error Checking and Correction (ECC) RAM uses a parity memory scheme to detect and fix memory errors that would otherwise cause memory errors when the data is read.
D: Rambus is a proprietary DRAM memory technology that uses an internal 16-bit data channel that operates in conjunction with a 400 MHz clock and allows Rambus to operate at much higher speeds than more conventional 64-bit memory buses.
