What kind of memory is used in portable devices?

The CompTIA A+ certification requires extensive knowledge of memory packages, pin counts, and memory functions. In this module, we’ll step through each memory package and describe the progression of the different memory types through the years. We’ll discuss packages such as DIMM, RIMM, SODIMM, and MicroDIMM, and we’ll also detail memory types such as SRAM, SDRAM, RDRAM, DDR, and DDR2.
