The programmable metallization cell, or PMC, is a new form of non-volatile computer memory being developed at Arizona State University and its spinoff, Axon Technologies. PMC is one of a number of technologies that are being developed to replace the widely used flash memory, providing a combination of longer lifetimes, lower power, and better memory density. Infineon Technologies, who licensed the technology in 2004, refers to it as conductive-bridging RAM, or CBRAM. NEC has a variant called “Nanobridge” and Sony calls their version “electrolytic memory”.

PMC is based on the physical re-location of ions within a solid electrolyte. A PMC memory cell is made of two solid metal electrodes, one relatively inert (e.g., tungsten) the other electrochemically active (e.g., silver or copper), with a thin film of the electrolyte between them. A control transistor can also be included in each cell.

When a negative bias is applied to the inert electrode, metal ions in the electrolyte, as well as some originating from the now-positive active electrode, flow in the electrolyte and are reduced (converted to atoms) by electrons from the inert electrode. After a short period of time the ions flowing into the filament form a small metallic "nanowire" between the two electrodes. The "nanowire" dramatically reduces the resistance along that path, which can be measured to indicate that the "writing" process is complete.

Tina Louise (born February 11, 1934) is an American actress, singer, and author. She is best known for her role as the "movie star" Ginger Grant on the television situation comedy Gilligan's Island (1964-1967).

Tatiana (Tina) Josivovna Chernova Blacker was born in New York City to a Jewish family. She was raised by her mother, Betty Horn Myers (1916-2011), a fashion model. Her father, Joseph Blacker, was a candy store owner in Brooklyn and later an accountant. The name "Louise" was supposedly added during her senior year in high school when she mentioned to her drama teacher that she was the only girl in the class without a middle name. He immediately picked the name "Louise" and it stuck. She attended Miami University in Oxford, Ohio. At the age of 17, Louise began studying acting, singing and dancing. During her early acting years, she was offered modeling jobs and appeared on the cover of several pinup magazines such as Adam, Sir! and Modern Man. Her later pictorials for Playboy (May 1958, April 1959) were arranged by Columbia Pictures studio in an effort to further promote the young actress. Her acting debut came in 1952 in the Bette Davis musical revue Two's Company, followed by roles in other Broadway productions, such as John Murray Anderson's Almanac, The Fifth Season, and Will Success Spoil Rock Hunter? She also appeared in such early live television dramas as Studio One, Producers' Showcase, and Appointment with Adventure.
