com BENEFITS 66% SPACE SAVINGS Reduced part count from 9 to 1 Reduced I/O count • 55% I/O Reduction Reduced trace lengths for lower parasitic capacitance Suitable for hi-reliability applications Laminate interposer for optimum TCE match GENERAL DESCRIPTION The 512MByte (4.
5Gb) SDRAM is a high-speed CMOS, dynamic random-access, memory using 9 chips containing 512M bits.
Each chip is internally configured as a quadbank DRAM with a synchronous interface.
Each of the chip’s 134,217,728-bit banks is organized as 8,192 rows by 2,048 columns by 8 bits.
Read and write accesses to the SDRAM are burst oriented; accesses start at a selected location and continue for a * This product is under development, is not qualified or characterized and is subject to change or cancellation without notice.
