IC DRAM Card

IC DRAM Cards These are special memory card, in a form-factor that is similar to PCMCIA. It was used on early ThinkPad 300 and 700 models. NOTE! To use non-parity memory on most Thinkpad 750/755 models it was necessary, before installing the memory, to enter BIOS setup and disable the memory parity check option

16MB IC DRAM Card

IC DRAM module is a JEIDA or JEDEC standard. Organised similar to 72-pin SIMM. It has 88 pins in two rows, staggered.
