Manufacturer:Winbond Description: The Samsung M390S2858DT1 is a 128M bit x 72 Synchro- nous Dynamic RAM high density memory module. The Sam- sung M390S2858DT1 consists of eighteen CMOS Stacked 128Mx4 bit Synchronous DRAMs in two TSOP-II 400mil pack- ages, three 18-bits Drive ICs for input control signal, one PLL in 24-pin TSSOP package for clock and one 2K EEPROM in 8- pin TSSOP package for Serial Presence Detect on a 168-pin glass-epoxy substrate. Two 0.22uF and one 0.0022uF decou- pling capacitors are mounted on the printed circuit board in parallel for each SDRAM. The M390S2858DT1 is a Dual In- line Memory Module and is intented for mounting into 168-pin edge connector sockets. Synchronous design allows precise cycle control with the use of system clock. I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable laten- cies allows the same device to be useful for a variety of high bandwidth, high performance memory system applications. |
