Abstract
A storage/logic array (SLA). In a programmable form (PSLA), the array includes a set of parallel, programmably segmentable column conductors and an orthogonal set of programmably segmentable row conductors. Each of a plurality of cell networks is associated with and coupled to a subset of the row conductors and a subset of the column conductors. At least one column conductor subset has an associated cell network which includes a storage element which is coupled to the associated column subset and row subset for that cell network. In a nonprogrammable form, the SLA is similar to the programmable form (PSLA) except that row and column conductors are segmented at predetermined locations, and cell networks are coupled to predetermined, associated subsets of the row and column conductors.

A programmable storage/logic array comprising
- A. a set of substantially parallel column conductors including a plurality of non-intersecting subsets,
- B. a set of substantially parallel row conductors including a plurality of non-intersecting subsets, said row conductors being orthognal to said column conductors,
- C. a plurality of cell networks, each of said cell networks being associated with one of said subsets of column conductors, and one of said subsets of row conductors,
- wherein at least one of said cell networks includes a storage element, and
- wherein at least one of said cell networks includes programmable cell contact means for selectively coupling said cell network to its associated row and column conductors, and
- wherein said storage element includes means for storing a signal representative of the binary state of one of the conductors of said coupled subsets of column and row conductors, and means for coupling said stored signal to one of the conductors of said coupled subsets of column and row conductors.
