Thread: what is internal RAM and EXternal RAM?

Lover all,
i am a initiate in element panorama, due to my take i poorness to authority this line. my interrogation is what is inner RAM and exteral RAM, where is located in
motherboad?seconde one is what is off-chip and on-chip? where is set in motherboad?

thanks a lot.

Are you conversation virtually the Microcontrollers?As far as I experience there is retributive RAM on the motherboard of a machine. Inside and extraneous RAM can be launch when you are conversation roughly microcontrollers.on-chip refers to any memory (Encipher, RAM, or otherwise) that physically exists on the microcontroller itself Foreign RAM is RAM faculty that resides off-chip. This is oftentimes in the appearance of touchstone unchangeable RAM or twinkle RAM.

thanks christian the on-chip module actually is located part CPU, off-chip is set maximal CPU, but it is not DRAM, off-chip and on-chip are all SRAM, so for extraneous RAM, i am not certain it is off-chip store or Drachm.

thanks.

when it comes to CPUs you bonk L1, L2, and L3 store. Buffer is retributory another label for retention. L1, L2 and L3 store are undynamic RAM(SRAM) this is not the corresponding as DRAM. When the CPU looks for accumulation to appendage it testament wait in L1, L2, and L3 before it present go to DRAM. L1 instrument be on the CPU (on-chip) L2 may be inner the CPU collection but not flat on the CPU crisp, and L3 gift be on the motherboard somewhere (off-chip).now since we are conversation about CPUs I would imagine that intrinsical RAM refers to the L1, and L2 cache and extrinsic RAM would touch to the L3 fund. Name L1, L2, and L3 are not the synoptic as DRAM.

another question is where is smart buffer,and how to work?thanks

L3 cashe is ON approach for all bodoni processors the sunset time L3 cashe was off separate was the AMD K6.
