A 512Mb diode-switch PRAM is developed in a 90nm CMOS technology. A core configuration, read/write circuit techniques, and a charge-pump system for the diode-switch PRAM are described. Through these schemes, the PRAM achieves read throughput of 266MB/S and maximum write throughput of 4.64MB/S with a 1.8V supply.

P‐73: A Novel LCD Backlight Unit using a Light‐guide Plate with High Fill‐factor Microlens Array and a Conical Microlens Array Sheet

Joohyung Lee; Jun-Bo Yoon; Joon-Yong Choi; Sang-Min Bae

In this paper, we have proposed a novel LCD backlight unit (BLU) composed of a light-guide plate (LGP) mounting high fill-factor microlens array and an optical sheet of conical microlens array with a slanted angle of 54.5°. The proposed BLU shows 13.6% improvement in the total luminance compared with the conventional BLU and the viewing angle of 108° (−42° ∼ 66°). We also have fabricated Ni-stamper with the microlens array pattern for injection molding, one of the cost-efficient methods for mass production.
