Abstract :
A 3.5-ns emitter-coupled logic (ECL) 16-kbit bipolar RAM with a power dissipation of 2 W, a cell size of 495 μm/SUP 2/, and a chip size of 20 mm/SUP 2/ has been developed. High performance is achieved using a high-speed Schottky barrier diode decoder with a pull-up circuit and a double-stage discharge circuit for a word-line driver. Small cell size is obtained using ultra-thin Ta/SUB 2/O/SUB 5/ film capacitors and 1-μm U-groove isolation technology. An access time of 3.5 ns in this 16-kb bipolar RAM is equivalent to an effective access time of 2.5 ns at the system level, due to an on-chip address buffer and latch.
