Q: Are memory controllers available?
A: RLDRAM II memory controllers are available from a variety of FPGA and 3rd party IP suppliers.
LLDRAM II devices are drop-in compatible.
Q: Are these packages lead-free?
A: The initial parts are packaged in 5/6 RoHS compliant µBGAs. GSI expects to offer qualified 6/6 RoHScompliant i.e., “green”) devices in early 2012.
Q: What temperature ranges are available?
A: GSI offers commercial (TJ: 0–90⁰C) and industrial (TJ: –40–+105⁰C) temperature range for all memories as
standard products. Industrial temperature operation can be specified by adding an “I” to the end of the part
number (e. g. “GS4576C36L-18I”).
Q: Are second sources available?
A: Yes. Micron provides equivalent devices today.
Q: What silicon technology is used?
A: GSI’s LLDRAM II devices use a standard 72nm DRAM wafer flow. It is qualified and in high volume
production.
Q: Does GSI offer model files?
A: Yes. GSI offers Verilog, BSDL, VHDL & IBIS models with each device.
