Abstract:

A memory cell comprising a memory region of amorphous silicon, such memory region having a first state of substantial electrical nonconductivity programmable to a second state of substantial electrical conductivity in response to an electrical programming signal applied thereto. The memory region is disposed over a metal Schottky contact, such as platinum-silicide (PtSi), formed in a support body. A first barrier layer comprising a refractory metal such as titanium-tungsten (TiW) is disposed between the memory region and Schottky contact. A first input terminal comprising a metal strip conductor, such as aluminum, is disposed over the memory region, with a second refractory metal barrier layer being disposed between the memory region and metal strip conductor. A second input terminal is disposed within the support body. With such arrangement, the material of the Schottky contact (PtSi) is substantially prevented from migrating or diffusing into the silicon memory region upon application of the electrical programming signal between the first and second input terminals, thereby preserving the structure of the metal contact and maintaining a low reverse bias leakage current for a Schottky diode comprising such metal contact.

Abstract:

An electronic gaming table adapted to host table games involving wagers includes a physical surface adapted for the play of live table games that include live players and the use of a live dealer and physical game components, multiple player terminals having separate processors, a master table controller in communication with each of the player terminal processors and adapted to control a plurality of electronic gaming table functions, and at least one interface in communication with the master table controller and one or more additional electronic gaming tables remotely located from the electronic gaming table. Each player terminal allows for a live player stationed thereat to participate in a first live table game directly at the electronic gaming table and also a second live table game remotely at a remotely located table. The first and second live table games can be different games, and can be played simultaneously.
