Abstract
A ROM memory circuit is disclosed having at least one electrical line, at least one keeper circuit electrically connected to the at least one electrical line, the keeper circuit including a first transistor, a terminal of the first transistor is driven by a dedicated control signal, wherein the dedicated control signal is configured to keep the voltage of the at least one electrical line at a first voltage.
Claims25
A semiconductor memory circuit comprising:
- at least one electrical line;
- and
- at least one keeper circuit electrically connected to the at least one electrical line, the keeper circuit including a first transistor, a terminal of the first transistor is driven by a dedicated control signal, wherein the dedicated control signal is configured to keep the voltage of the at least one electrical line at a first voltage.
A method for stabilizing voltage on a target line in a memory circuit, comprising:
- electrically coupling the target line to a source having a first voltage via a transistor having a gate, the gate having a threshold voltage,
- charging the target line to a second voltage,
- selectively generating a dedicated signal exceeding the threshold voltage, and applying the signal to the gate to operate the transistor in accordance with the signal,
- wherein, the voltage on the target line is maintained at the first voltage via a connection of the target line to the source while the signal is applied.
