摘要： A memory circuit includes a memory cell and a data circuit. In a write operation of the memory cell, the data circuit is configured to provide a first write logical value to the first output of the data circuit and to provide a second write logical value to the second output of the data circuit. The first write logical value is different from the second write logical value. In a read operation of the memory cell, the data circuit is configured to provide a same logical value to the first output and the second output of the data circuit.

摘要： A current flowing through a voltage line and/or a data line in a column of a tracking circuit is determined. A threshold tracking time delay of the tracking circuit is determined. Based on the determined current handled by the voltage line and/or the data line and the determined threshold tracking time delay, a plurality of columns in the tracking circuit, a number of first cells in each column of the plurality of columns, and a number of second cells in the each column of the plurality of columns are determined.

摘要： Embodiments of the invention are related to sense amplifiers. In an embodiment involving a sense amplifier used with a memory cell, signals BL, ZBL, SN and SP are pre-charged and equalized to a voltage reference, e.g., Vref, using an equalizing signal. A compensation signal, e.g., SAC, is applied to compensate for the mismatch between transistors in the sense amplifier. The word line WL is activated to connect the memory cell to a bit line, e.g., bit line ZBL. Because the memory cell shares the charge with the connected bit line ZBL, it causes a differential signal to be developed between bit lines BL and ZBL. When enough split between bit lines BL and ZBL is developed, signals SP and SAE are raised to VDD (while signal SN has been lowered to VSS) to turn on the sense amplifier and allow it to function as desire. Other embodiments and exemplary applications are also disclosed.
