  • Patent number: 9875788
    Abstract: A 5 Transistor Static Random Access Memory (5T SRAM) is designed for reduced cell size and immunity to process variation. The 5T SRAM includes a storage element for storing data, wherein the storage element is coupled to a first voltage and a ground voltage. The storage element can include symmetrically sized cross-coupled inverters. A single access transistor controls read and write operations on the storage element. Control logic is configured to generate a value of the first voltage a write operation that is different from the value of the first voltage for a read operation.

  • Patent number: 9865330
    Abstract: Stable SRAM cells utilizing Independent Gate FinFET architectures provide improvements over conventional SRAM cells in device parameters such as Read Static Noise Margin (RSNM) and Write Noise Margin (WNM). Exemplary SRAM cells comprise a pair of storage nodes, a pair of bit lines, a pair of pull-up devices, a pair of pull-down devices and a pair of pass-gate devices. A first control signal and a second control signal are configured to adjust drive strengths of the pass-gate devices, and a third control signal is configured to adjust drive strengths of the pull-up devices, wherein the first control signal is routed orthogonal to a bit line direction, and the second and third control signals are routed in a direction same as the bit line direction. RSNM and WNM are improved by adjusting drive strengths of the pull-up and pass-gate devices during read and write operations.

The second dummy structure has a third sidewall and a fourth sidewall that are separated by a second width. The second width is substantially greater than the first width. The first dummy structure is used to form a first pair of fins separated by approximately the first width. The second dummy structure is used to form a second pair of fins separated by approximately the second width.
