    摘要: Techniques are provided for a computer-readable medium encoding a memory using a back-gate controlled asymmetrical memory cell. In one aspect, the cell includes five transistors and can be employed for static random access memory (SRAM) applications. An encoded inventive memory circuit can include a plurality of bit line structures, a plurality of word line structures that intersect the plurality of bit line structures to form a plurality of cell locations, and a plurality of cells located at the plurality of cell locations. Each cell can be selectively coupled to a corresponding one of the bit line structures under control of a corresponding one of the word line structures. Each cell can include a first inverter having first and second field effect transistors (FETS) and a second inverter with third and fourth FETS that is cross-coupled to the first inverter to form a storage flip-flop. One of the FETS in the first inverter can be configured with independent front and back gates and can function as both an access transistor and part of one of the inverters.

    摘要: Techniques are provided for employing independent gate control in asymmetrical memory cells. A memory circuit, such as an SRAM circuit, can include a number of bit line structures, a number of word line structures that intersect the bit line structures to form a number of cell locations, and a number of asymmetrical memory cells located at the cell locations. Each of the asymmetrical cells can be selectively coupled to a corresponding one of the bit line structures under control of a corresponding one of the word line structures. Each of the cells can include a number of field effect transistors (FETS), and at least one of the FETS can be configured with separately biased front and back gates. One gate can be biased separately from the other gate in a predetermined manner to enhance read stability of the asymmetrical cell.

    摘要: Disclosed is an eight transistor static random access memory (SRAM) device, comprising first and second inverters, a first bit line, a first complement bit line, a pair of write access transistors, and a pair of read access transistors. Each of the first and second inverters includes a respective pair of transistors, and has a respective data node. Each of a first and a second of the access transistors has a source, a drain, a front gate, and a back gate. The first access transistor is coupled to the first bit line, and the second access transistor is coupled to the first complement bit line. The back gate of the first access transistor is coupled to the data node of the first inverter; and the back gate of the second access transistor is coupled to the data node of the second inverter. This increases the difference between the threshold voltages of the first and second access transistors.

    摘要: Techniques are provided for asymmetrical SRAM cells which can be improved, for example, by providing one or more of improved read stability and improved write performance and margin. A first inverter and a second inverter are cross-coupled and configured for selective coupling to true and complementary bit lines under control of read and write word lines. The first inverter is formed by a first, n-type, FET (NFET) and a second, p-type, FET (PFET). Process and/or technology approaches can be employed to adjust the relative strength of the FETS to obtain, for example, read margin, write margin, and/or write performance improvements.
