🗑
RAM: Doubles the data rate of DDR. In addition to double pumping, it modifies the way that data is processed and can transfer twice as much data as DDR SDRAM.   DDR2  
🗑
This RAM uses switching circuitry rather than capacitors and can hold a charge without a constant refresh. It requires more components per bit making it more expensive, however it’s quicker than DRAM.   SRAM (Static RAM)
