MICRON MT48LC16M16A2B4-6A:G DRAM, SDR, 256 Mbit, 16M x 16bit, 166 MHz, VFBGA, 54 Pins

MT48LC16M16A2B4-6A:G is a 256Mb SDR SDRAM. It is a high-speed CMOS, dynamic random-access memory containing 268,435,456 bits. It is internally configured as a quad-bank 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 an ACTIVE command, which is then followed by a READ or WRITE command. The address bits registered coincident with the ACTIVE command are used to select the bank and row to be accessed. The address bits registered coincident with the READ or WRITE command are used to select the starting column location for the burst access.
