Datasheet - AS4C32M16SB-7TCN

The Alliance Memory 512Mb SDRAM is a high-speed CMOS synchronous DRAM containing 512 Mbits. It is internally configured as 4 Banks of 8M 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.
