최대 작동 온도 = +70 °C The Alliance Memory 64Mb SDRAM is a high-speed CMOS synchronous DRAM containing 64 Mbits. It is internally configured as 4 Banks of 1M word x 16 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal, CLK). Read and write accesses to the SDRAM are burst oriented accesses start at a selected location and continue for a programmed number of locations in a programmed sequence. Accesses begin with the registration of a Bank Activate command which is then followed by a Read or Write command.Fast access time from clock: 4.5/5.4/5.4 ns Fast clock rate: 200/166/143 MHz Fully synchronous operation Internal pipelined architecture 1M word x 16-bit x 4-bank
