MT48LC16M16A2P

Product Summary

The MT48LC16M16A2P is a high-speed CMOS, dynamic random-access memory containing 268,435,456 bits. The MT48LC16M16A2P 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 x4s 67,108,864-bit banks is organized as 8192 rows by 2048 columns by 4 bits. Each of the x8s 67,108,864-bit banks is organized as 8192 rows by 1024 columns by 8 bits. Each of the x16s 67,108,864-bit banks is organized as 8192 rows by 512 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 (BA[1:0] select the bank; A[12:0] 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.
