288Pin DDR4 2133 ECC U-DIMM
8GB Based on 512Mx8
TS1GLH72V1H
Description
DDR4 ECC U-DIMMs are high-speed, low power memory
modules that use 512Mx8bits DDR4 SDRAM in FBGA
package and a 4K-bit serial EEPROM on a 260-pin
printed circuit board. DDR4 ECC U-DIMMs are Dual
In-Line memory modules and are intended for mounting
into 260-pin edge connector sockets.
The synchronous design allows precise cycle control with
the use of system clock. Data I/O transactions are
possible on both edges of DQS. The large range of
operation frequencies and programmable latencies allow
the same device to be useful for a variety of high
bandwidth and high performance memory system
applications.
