    摘要: A memory system (200) has an array of addressable storage elements (210) arranged in a plurality of rows and a plurality of columns, and decoding circuitry (220, 230) coupled to the array of addressable storage elements (210). The decoding circuitry (220, 230), in response to decoding a first address, accesses a first storage element of a first row of the plurality of rows, and, in response to decoding a second address consecutive to the first address, accesses a second storage element of a second row of the plurality of rows. The second row of the plurality of rows is different from the first row of the plurality of rows. By implementing a memory system wherein consecutive addresses correspond to storage elements of different rows, read disturb stresses along a single row can be minimized.

    摘要: A semiconductor fabrication method includes forming a semiconductor structure including source/drain regions disposed on either side of a channel body wherein the source/drain regions include a first semiconductor material and wherein the channel body includes a migration barrier of a second semiconductor material. A gate dielectric overlies the semiconductor structure and a gate module overlies the gate dielectric. An offset in the majority carrier potential energy level between the first and second semiconductor materials creates a potential well for majority carriers in the channel body. The migration barrier may be a layer of the second semiconductor material over a first layer of the first semiconductor material and under a capping layer of the first semiconductor material. In a one dimensional migration barrier, the migration barrier extends laterally through the source/drain regions while, in a two dimensional barrier, the barrier terminates laterally at boundaries defined by the gate module.

    摘要: An electronic device includes a memory cell that utilizes a bi-directional low impedance, low voltage drop full pass gate to connect a bit cell to a bit write line during a write phase, and during a read phase the full pass gate can remain off and a high input impedance read port can acquire and transmit the logic state stored by the memory cell to another subsystem. The full pass gate can be implemented by connecting a P type metal semiconductor field effect transistor (PMOS) in parallel with an NMOS device and driving the gates of the transistors with a differential signal. When a write operation requires a current to flow in a first direction, the PMOS device provides a negligible voltage drop, and when the write operation requires current to flow in a second or the opposite direction, the NMOS device can provide a negligible voltage. This bi-directional low voltage drop low loss switch can increase the write margin of the memory cell wherein the high impedance read port can provide increased isolation for the stored value during the read phase increasing the performance of the memory cell.
