No, there isn't a labeled image showing the specific function of each plate in PC100 RAM.

I'm gathering information about the specifications of a PC100 RAM module to understand how it communicates with an Arduino and other components.
DDR operates using extremely brief signal bursts, with each bit lasting only nanoseconds. The system handles large amounts of data, but adding information to a RAM stick often causes errors and corruption due to mismatched trace lengths and other issues. Whatever you're dealing with, it's probably too slow to read bytes from the RAM and process them correctly for your Arduino.
I wasn't implying I possess anything special. My goal was to use an Arduino to capture data from a stick and send it to another RAM stick, making the PC appear to have more memory than it actually does. I was trying to trick the system into thinking it had extra RAM. Could you get a labeled image? I believe I understand what I'm working on... Apologies for any confusion.
Your Arduino or PIC runs at 16 .. 40 Mhz ... DDR4 runs at 1066 ... 1600 Mhz double clocked ... that's what 2133 ... 3600 Mhz means. There's a memory controller (inside the processor) and there's ram (which is "dumb" in the sense that it receives commands from memory controller, loads the data from ram banks and puts it on the pins and sends it in a burst to the memory controller. In order to intercept some commands from the memory controller, your microcontroller has to be fast enough to read those commands and answer within nanoseconds back to the memory controller, otherwise the memory controller will think the memory stick is faulty, that it times out. With an arduino, probably the quickest you could send a reply back would be in the order of 2-3 milliseconds ... 2-3 THOUSAND times slower ... and then it has to clock in bits on 64 data pins once every few nanoseconds ... a microcontroller can't do that. You can do maybe up to 1-5 MB/s of data sustained with a cheap arduino / pic microcontroller You're basically thinking of making something in between ... a bridge .. show up to cpu as ram stick, but also act like memory controller for a ram stick ... people use FPGAs with built in memory controllers but the ones capable of DDR4 are expensive
