Abstract

The charge storage elements (3) of an array (2) are arranged in columns and rows and each column is coupled to an associated column conductor (4). Each storage element (3) in a row is coupled to an associated second conductor by a first rectifying element (D1) and to an associated third conductor by a second rectifying element (D2). Each row shares its second and third conductors (5a, 5b, 6a, 6b) with any adjacent rows. One of the two conductors of each row forms a row conductor (5a, 5b) and the other (6a, 6b) one of first and second reference conductors (6a and 6b). Adjacent row conductors (5a, 5b) are separated by a reference conductor (6a or 6b). Each first reference conductor (6a) is separated from any other first reference conductor (6a) by two row conductors (5a, 5b) and a second reference conductor (6b). The rectifying elements (D1' and D2') associated with a respective row conductor (5a, 5b) are oppositely oriented to the rectifying elements (D1" and D2") associated with any adjacent row conductors (5b, 5a). In operation, first and second different reference voltages (V.sub.- and V.sub.+) are applied to the first and second reference conductors (6a and 6b) respectively and …
