256Mb (x16)-SDR Synchronous DRAM 16M x 16 bit Synchronous DRAM (SDRAM) Overview The 256Mb SDRAM is a high-speed CMOS synchronous DRAM containing 256 Mbits.
It is internally configured as 4 Banks of 4M 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 BankActivate command which is then followed by a Read or Write command.
The SDRAM provides for programmable Read or Write burst lengths of 1, 2, 4, 8, or full pag...
