Abstract
A circuit structure for a matrix of EEPROM memory cells, being of a type which comprises a matrix of cells including plural rows and columns, with each row being provided with a word line and a control gate line and each column having a bit line; the bit lines, moreover, are gathered into groups or bytes of simultaneously addressable adjacent lines. Each cell in the matrix incorporates a floating gate transistor which is coupled to a control gate, connected to the control gate line, and is connected serially to a selection transistor; also, the cells of each individual byte share their respective source areas, which areas are structurally independent for each byte and are led to a corresponding source addressing line extending along a matrix column.
