Abstract:
1. A method for accessing a memory, comprising: storing data in an array of memory cells, wherein each memory cell comprises a first access device, a second access device, and a storage element connected to the first and second access devices; accessing a plurality of memory cells along a row direction of the array of memory cells using a first arrangement of access wiring comprising wordlines and bitlines connected to the memory cells, wherein the word lines of the first arrangement of access wiring are configured to control activation and deactivation of the first access devices of the memory cells, and wherein the bit lines of the first arrangement of access wiring are switchably connected to the storage elements of the memory cells through activation of the first access devices; and accessing a plurality of memory cells along a column direction of the array of memory cells using a second arrangement of access wiring comprising word lines and bit lines connected to the memory cells, wherein the word lines of the second arrangement of access wiring are configured to control activation and deactivation of the second access devices of the memory cells, and wherein the bit lines of the second arrangement of access wiring are switchably connected to the storage elements of the memory cells through activation of the second access devices; wherein the word lines of the first arrangement of access wiring are disposed orthogonal to the word lines of the second arrangement of access wiring, and wherein the bitlines of the first arrangement of access wiring are disposed orthogonal to the bit lines of the second arrangement of access wiring, and wherein accessing the plurality of memory cells along the row direction and accessing the plurality of memory cells along the column direction are each performed using a single access operation to enable independent access to rows and columns of memory cells in the array of memory cells.
