My data storage mediums, post 17 (36th week)
I had another, much better search through the bad RAM bin and was able to find regular SDR SDRAM and a DDR-3 stick of RAM which helps me to fill out a few more empty spots on my silicon cornice (that’s what I’m going to call it from now on as most of the stuff going on there is going to be silicon based).
The DDR-3 stick has 240 pins which is the same amount as DDR-2 but the key has changed positions as to prevent putting the wrong memory in, the benefit with DDR-3 is that there are low power modules available for cases where lower power consumption is required, this is done by reducing the voltage that the silicon needs to store the data but it may have some disadvantages like slightly slower access speeds.
Mentioned in my previous post about SDRAM, it stands for Synchronous Dynamic Random Access Memory which means that the operation of its pin interface is coordinated with an external clock signal, some of the earlier DRAM modules were often synchronized with the CPU clock speed, there were two types of operation which was called synchronous where changes on control inputs are recognised on the rising edge of its clock input unlike asynchronous interface in which input control signals have a direct effect on internal functions delayed only by the trip across its semiconductor pathways, this SDR SDRAM was eventually eclipsed by DDR memory which was made by IBM.
Thank you for reading this Friday‘s post and I hope you have a great day, if you have any queries, thoughts about the format, additional information or to point out a mistake, please put them in the comments :)

All of my RAM right now (there wasn’t any laptop RAM in the bad ram bin that I didn’t yet have), from left to right is SDR SDRAM, DDR-1 DIMM, DDR-2 DIMM, DDR-3 DIMM and DDR-4 DIMM, I doubt I’ll get DDR-5 of any kind because they rarely come across it due to it being so modern
Closer look at the SDR SDRAM, it holds 128MB of data
Closer look at the DDR-3 DIMM, it holds 4GB of data
