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 congured as a quad-
bank 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
64Mx72 Synchronous DRAM
FEATURES
High Frequency = 100, 125, 133MHz
Package:
219 Plastic Ball Grid Array (PBGA), 32 x 25mm
3.3V ±0.3V power supply for core and I/Os
Fully Synchronous; all signals registered on positive
edge of system clock cycle
