Abstract
A transposable memory architecture for providing equally fast access to stored data in two or more dimensions. This architecture is provided by orthogonal wiring of access devices, word lines and bit lines with independent random accessing capability for data in each direction. The transposable memory architecture (TMA) cell directly inplements the TMA architecture using only one access device per dimension of access. This invention also describes multiple transposable memory architecture (MTMA) device for additional data path flexibility. The read and write operations described provide access and cycle times approximately equivalent to those for a convention one-dimension RAM.
