The DIMM is composed of eight TMS664814DGE 8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic thin small-outline package (TSOP) mounted on a substrate with decoupling capacitors. See the TMS664814 data sheet (literature number SMOS695). The TM16LR64JFN is a 128M-byte, 168-pin DIMM. The DIMM is composed of sixteen TMS664814DGE 8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic TSOP mounted on a substrate with decoupling capacitors. operation The TM8LR64JFN operates as eight TMS664814DGE devices that are connected as shown in the TM8LR64JFN functional block diagram. The TM16LR64JFN operates as 16 TMS664814DGE devices connected as shown in the TM16LR64JFN functional block diagram.
