GENERAL DESCRIPTION
SiliconTech T4S32M4-4xxxx bits banks Single Data Rate (SDR) Synchronous Dynamic (SDRAM) Tower. Tower consists 3.3V CMOS bits banks SDRAMs 54-pin 400-mil TSOP-II packages mounted stacks stack PCBs. SDRAMs soldered onto both sides PCBs using high temperature solder shown following page. Tower then mounted onto module using temperature solder. stacking technology patented SiliconTech Tower (Patent 5,514,907). Tower used place single allow high capacity memory modules without increasing height memory module.
