Memory Modules

Types of Memory Modules :
1. S I M M 
Short for Single In-Line Memory Module, that module or memory chip embedded on side of the circuit PCB. The memory of this type only have a total of leg (pin) as lots of as 30 and 72.
SIMM 30 pins in the type of FPM DRAM, widely used in processor-based systems 386 and 486 generations of the finish of the first generation. 30 pins SIM card capacity 1MB, 4MB and 16MB.
Meanwhile, 70-pin SIMMs can be either FPM DRAM and EDO DRAM shared with the late-generation processor 486 and Pentium. 70 pin SIMM is produced on the capacity of 4MB, 8MB, 16MB, 32MB, 64MB and 128MB.

2. D I M M 
Short for Dual In-Line Memory Module, that module or memory chip embedded on both sides of the PCB. DIMM memory is produced in three different forms, namely the amount of feet 168 and 184.
DIMM 168-pin can be either Rapid Page, EDO and ECC SDRAM. While the type of DIM 184 pin DDR SDRAM.

3. SODIMM 
Short for Small Outline Dual In-Line Memory Module. Memory is fundamentally similar to DIMMs, but the difference is in their use. If the DIMM is used on a PC, then SO DIMM used on laptop computer / laptop.
SODIMM produced in types, first type has a total of 72 pin, and only 144 numbered pieces

4. RIMM / SORIMM 
RIMM and SORIMM is a kind of memory that is made by Rambus. RIMM is fundamentally the same with similar SORIMM DIMM and SODIMM.
Because the use of Rambus know-how, which prioritizes famous speeds, this memory is so hot so rapid Rambus parties will need to add aluminum to help remove the heat generated by this memory.
