Multi-port Memory Invention

Multi-port Memory Invention

Multi-port Memory Invention April 25, 2022 by Lance In 1990 I filed a patent on a new kind of multiport memory. It exploits the fact that we store words rather than just bits in memories. By storing the words in clever ways one can tolerate collisions among accesses...
A linear circuit theory conservation theorem

A linear circuit theory conservation theorem

A linear circuit theory conservation theorem April 25, 2022 by Lance The theoretical work of which I am most proud was on a linear circuit theory conservation theorem that produced tight bounds on the performance of circuits composed of linear elements. The basic...

The first modelocked semiconductor laser diodes

The first modelocked semiconductor laser diodes April 25, 2022 by Lance I was a member of the team that first modelocked a semiconductor laser. We did it first with GaAlAs and then with GaInAsP. These experiments generated pulses more than an order of magnitude...
