Abstract: A metal-insulator-semiconductor (MIS) resistive random access memory (RRAM) (MIS RRAM) device and MIS RRAM bit cell circuit are disclosed. A RRAM bit cell includes a RRAM device that can store a memory state and an access transistor to control access to the RRAM device. The RRAM device stores data as an electrical resistance formed in an oxide layer by applying a voltage differential between the top and bottom electrodes through the access transistor to generate an electric field in the oxide layer. This structure is similar to a metal gate formed over a channel region of a transistor. Forming the bottom electrode of the MIS RRAM device in a semiconductor structure may allow the dimensions of the electrodes of the MIS RRAM device to be scaled down to the dimensions of a transistor gate, because the MIS RRAM device structure can be fabricated with the transistor in a compatible process.

Abstract: Non-volatile (NV) memory (NVM) matrix circuits employing NVM circuits for performing matrix computations are disclosed. In exemplary aspects disclosed herein, an NVM matrix circuit is provided that has a plurality of NVM storage string circuits each comprising a plurality of NVM bit cell circuits each configured to store a memory state. Each NVM bit cell circuit has a stored memory state represented by a resistance, and includes a transistor whose gate node is coupled to a word line among a plurality of word lines configured to receive an input vector of 1×m size for example. Activation of the gate of a given NVM bit cell circuit controls whether its resistance is contributed to a respective source line. This causes a summation current to be generated on each source line based on the weighted summed contribution of each NVM bit cell circuit's resistance to its respective source line.

Abstract: A FinFET having a backgate and a barrier layer beneath the fin channel of the FinFET, where the barrier layer has a bandgap greater than that of the backgate. The barrier layer serves as an etch stop layer under the fin channel, resulting in reduced fin channel height variation. The backgate provides improved current control. There is less punchthrough due to the higher bandgap barrier layer. The FinFET may also include deeply embedded stressors adjacent to the source/drain diffusions through the high bandgap barrier layer.

Abstract: Static random access memories (SRAM) with read-preferred cell structures and write drivers are disclosed. In one embodiment, the SRAM has a six transistor bit cell. The read-preferred bit cell is implemented by providing two inverters, each having a pull up transistor, a pull down transistor and a pass gate transistor. Each pull up transistor is associated with a feedback loop. The feedback loop improves random static noise margin. Each transistor has a width and a length. The lengths of the pass gate transistors are increased. The widths of the pull down transistors are equal to one another and also equal to the widths of the pass gate transistors. The widths of the pass gate and pull down transistors may also be increased relative to prior designs. A write assist circuit may also be used to improve performance.
