摘要： A first clock is received by a memory macro. In response to a first clock transition of the first clock, a first transition of a second clock and of a third clock is generated. A tracking transition of a tracking signal is caused by the second clock. Based on a later transition of a second clock transition of the first clock and the tracking transition of the tracking signal, a second transition of the third clock is generated. The third clock is for use by an input-output of the memory macro.

摘要： A non-volatile memory (NVM) cell splits its basic functions, i.e. program, erase, read and control, among a four PMOS transistor structure, allowing independent optimization of each cell function. The cell structure also includes an embedded static random access memory (SRAM) cell that utilizes a latch structure to preprogram data to be written to the cell and a plurality of cascoded NMOS pass gates. The cell structure reduces total programming time and provides the flexibility of programming the entire cell array simultaneously or one row or sector of the array at a time.

摘要： A clock generator includes a first input end and a second input end. The first input end is capable of receiving a first clock signal including a first state transition and a second state transition defining a first pulse width. The second input end is capable of receiving a second clock signal having a third state transition. A time period ranges from the first state transition to the third state transition. The clock generator can compare the first pulse width and the time period. The clock generator can output a third clock signal having a second pulse width ranging from a fourth state transition to a fifth state transition. The fifth state transition of the third clock signal is capable of being triggered by the second state transition of the first clock signal or the third state transition of the second clock signal depending on the comparison of the first pulse width and the time period.

摘要： A method of making a non-volatile memory (NVM) cell structure includes the formation of a first NVM cell, a second NVM cell and an SRAM cell that includes first and second data nodes. A first pass gate structure is connected between the first NVM cell and the first data node of the SRAM cell, the first pass gate structure being responsive to first and second states of a first pass gate signal to respectively couple and decouple the first NVM cell and the SRAM cell. A first equalize structure is formed to connect the first pass gate structure and the first NVM cell and is responsive to a first equalize signal to connect the first NVM cell to ground. A second pass gate structure is connected between the second NVM cell and the second data node of the SRAM cell, the second pass gate structure being responsive to first and second states of a second pass gate signal to respectively couple and decouple the second NVM cell and the SRAM cell. A second equalize structure is connected between the second pass gate structure and the second NVM cell, the second equalize structure being responsive to a second equalize signal to connect the second NVM cell to ground. Appropriate biasing conditions are applied to the NVM cell structure to implement program/operations.
