Abstract
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.
