From the manufacturer:

The EL6YG1A16 is 128Mx64 bits DDR3 SDRAM
Module, The module is composed of sixteen 64Mx8
bits CMOS DDR3 SDRAMs in FBGA package and
one 2Kbit EEPROM in 8pin TSSOP(TSOP) package
on a 240pin glass–epoxy printed circuit board.
The EL6YG1A16 is a Dual In-line Memory
Module and intended for mounting onto 240-pins 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 operating frequencies, programmable
latencies and burst lengths allow the same device to
be useful for a variety of high bandwidth, high
performance memory system applications.
