A 380 ps, 9.5 mW Josephson 4-Kbit RAM operated at a high bit yield
TL;DR: In this article, a Josephson 4-Kbit RAM with improved component circuits and a device structure having two Nb wiring layers was developed, where a resistor coupled driver and sense circuit were improved to have wide operating margins.
Journal ArticleDOI
A single flux quantum standard logic cell library
TL;DR: A new cell-based circuit design for single flux quantum (SFQ) circuit, called CONNECT cell library, which can easily expand designable circuit scale without the time-consuming dynamic simulations of whole circuits.
Journal ArticleDOI

Noboru Sakimura,Tadahiko Sugibayashi,Takeshi Honda,Hiroaki Honjo,S. Saito,Tetsuhiro Suzuki,Nobuyuki Ishiwata,Shuichi Tahara +7 more
TL;DR: This paper describes newly developed magnetic random access memory (MRAM) cell technology suitable for high-speed memory macros embedded in next-generation system LSIs: a two-transistor one-magnetic tunneling junction (2T1MTJ) cell structure, a write-line-inserted MTJ, and a 5T2MTJ cell structure.
Journal ArticleDOI
High-temperature superconducting edge-type Josephson junctions with modified interface barriers
TL;DR: In this article, the fabrication, electrical characteristics, and microstructure of high-temperature superconducting edge-type Josephson junctions with modified interface barriers are described, which are formed by surface modification of the YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// base layer.
Journal ArticleDOI
