512MB Registered DDR DIMM with ECC
General Description
The CM72SD512ARLP is a Double Data Rate SDRAM Dual Inline
Memory Module (DIMM), designed for applications in which both per-
formance and density are critical. This DIMM includes Error Checking
and Correcting (ECC) for maximum reliability, and has registered address
and control signals to enable fully configured systems.
These DIMMs are constructed using nine 512MBit (64Mx8) DDR
SDRAMs in TSOP-II packages, and are fully compliant with JEDEC
specifications.
The module also includes an EEPROM to support Serial Presence Detect
(SPD) requirements. Decoupling capacitors are mounted on the printed
circuit board for each DDR SDRAM device, and series termination is
provided on all clock and data lines.
The synchronous design of these Corsair SDRAM DIMMs allows precise
cycle control with the use of the system clock. Two I/O transactions are
possible on every clock cycle due to the use of double data rate RAMs. The
high clock frequency and high density of this device enable a high level of
performance to be achieved in advanced workstations and servers.
