Description Placement
The TX1066QLJ-2GK consists of 2pcs 1GB DDR2
SDRAM module. The 1GB module is a 128M x 64bits
DDR2-800 Unbuffered DIMM. The 1GB module consists
of 16 pcs 64Mx8bits DDR2 SDRAMs in 60 ball FBGA
packages and a 2048 bits serial EEPROM on a 240-pin
printed circuit board. The 1GB module is a Dual In-Line
Memory Module and is intended for mounting into
240-pin edge connector sockets.

Synchronous design allows precise cycle control with the
use of system clock. Data I/O transactions are possible
on both edges of DQS. Range of operation frequencies,
programmable latencies allow the same device to be
useful for a variety of high bandwidth, high performance
memory system applications.
