DATA SHEET
512MB Registered SDRAM DIMM
EBS51RC4ACFC (64M words × 72 bits, 1 bank)
Description
Features
The EBS51RC4ACFC is 64M words × 72 bits, 1 bank
Synchronous Dynamic RAM Registered Module,
mounted 18 pieces of 256M bits SDRAM sealed in
TSOP package. This module provides high density
and large quantities of memory in a small space
without utilizing the surface mounting technology.
Decoupling capacitors are mounted on power supply
line for noise reduction.
Fully compatible with 8 bytes DIMM: JEDEC

Lead pitch: 1.27mm
3.3V power supply
Clock frequency: 133MHz (max.)
LVTTL interface
Data bus width: × 72 ECC
Single pulsed /RAS
4 Banks can operates simultaneously and
independently
Burst read/write operation and burst read/single write
operation capability
Programmable burst length (BL): 1, 2, 4, 8
2 variations of burst sequence
Sequential
Interleave
Programmable /CAS latency (CL): 2, 3
Registered inputs with one clock delay
Byte control by DQMB
Refresh cycles: 8192 refresh cycles/64ms
2 variations of refresh
Auto refresh
Self refresh
1 piece of PLL clock driver, 3 pieces of register driver
and 1 piece of serial EEPROM (2k bits) for Presence
Detect (SPD) on PCB.
