What is the mean of DDR RAM ?
Double-Data-Rate Synchronous Dynamic Random Access Memory, better known as DDRDDRDDR SDRAM or DDRDDRDDR RAMRAMRAM for short, is a type of very fast computer memory. DDRDDRDDR RAMRAMRAM is based on the same architecture as SDRAM, but utilizes the clock signal differently to transfer twice the data in the same amount of time. In a computer system. the clock signal is an oscillating frequency used to coordinate interaction between digital circuits. Simply put, it synchronizes communication. Digital circuits designed to operate on the clock signal may respond at the rising or falling edge of the signal. SDRAM memory chips utilized only the rising edge of the signal to transfer data, while DDRDDRDDR RAMRAMRAM transfers data on both the rising and falling edges of the clock signal. Hence, DDRDDRDDR RAMRAMRAM is essentially twice as fast as SDRAM. RAMRAMRAM speed works in conjunction with the front side bus (FSB) of a computer system. The FSB is the two-way data channel that sends information
