SDR SDRAM
Typical clock frequencies are 100 and 133 MHz.
Originally simply known as SDRAM, single data rate SDRAM can accept one command and transfer one word of data per clock cycle.
Chips are made with a variety of data bus sizes (most commonly 4, 8 or 16 bits),
but chips are generally assembled into 168-pin DIMMs that read or write 64 (non-ECC) or 72 (ECC) bits at a time.
