Abstract :
An on-chip boosted power supply is necessary for ease of layout and high speed in high density DRAMs. The technique of TTL conversion is a key to designing high speed DRAMs for 3-V operation. The authors present the generation and regulation of an on-chip power supply (V/sub pp/) within 50 mV of the optimum level during operation for a given V/sub cc/. In addition to the regulated V/sub cc/ scheme, improved interface circuit techniques are employed to achieve fast input and output conversion with good noise margins. An experimental 64-Mb DRAM is designed. A typical access time of 35 ns is obtained by measurement.<>
