MT48LC32M16A2TG-75 Datasheet



The MT48LC32M16A2TG-75 is a high-speed CMOS, dynamic random-access memory containing 536,870,912 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). Each of the x4’s 134,217,728-bit banks is organized as 8,192 rows by 4,096 columns by 4 bits. Each of the x8’s 134,217,728-bit banks is organized as 8,192 rows by 2,048 columns by 8 bits. Each of the x16’s 134,217,728-bit banks is organized as 8,192 rows by 1,024 columns by 16 bits. 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 (BA0, BA1 select the bank; A0-A12 select the row). The address bits registered coincident with the READ or WRITE command are used to select the starting column location for the burst access.
