Alliance Memory AS4C8M16SA-7TCN, SDRAM 128Mbit Surface Mount, 166MHz, 3 V to 3.6 V, 54-Pin TSOP [AS4C8M16SA-7TCN]; 230-8440

The Alliance Memory 128Mb SDRAM is a high-speed CMOS synchronous DRAM containing 128 Mbits. It is internally configured as 4 Banks of 2M 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.
