  • Patent number: 6274928
    Abstract: A 16 megabit (224) or greater density single deposition layer metal Dynamic Random Access Memory (DRAM) part is described which allows for a die that fits within an industry-standard 300 ml wide SOJ (Small Outline J-wing) package or a TSOP (Thin, Small Outline Package) with little or no speed loss over previous double metal deposition layered 16 megabit DRAM designs. This is accomplished using a die architecture which allows for a single metal layer signal path, together with the novel use of a lead frame to remove a substantial portion of the power busing from the die, allowing for a smaller, speed-optimized DRAM. The use of a single deposition layer metal results in lower production costs, and shorter production time.
