Abstract
A memory device includes a memory cell and an amplifier. The memory cell is configured to store a first data bit. The amplifier is configured to generate a first data signal at a first node according to the first data bit, and configured to charge the first node according to a precharge signal. After the first node is charged according to the precharge signal, the amplifier is further configured to discharge the first node according to the precharge signal.
Claims20
A memory device, comprising:
- a memory cell configured to store a first data bit;
- and
- an amplifier configured to generate a first data signal at a first node according to the first data bit, and configured to charge the first node according to a precharge signal,
- wherein after the first node is charged according to the precharge signal, the amplifier is further configured to discharge the first node according to the precharge signal,
- wherein the amplifier comprises:
- a first switch coupled to a second node and controlled by the precharge signal;
- and
- a second switch coupled between the first node and the second node.
A memory device, comprising an amplifier, the amplifier comprising:
- a first switch, a first terminal of the first switch being coupled to a first node, a second terminal of the first switch being coupled to a second node, and a control terminal of the first switch being coupled to a third node;
- a second switch, a first terminal of the second switch being coupled to the third node, a second terminal of the second switch being coupled to the second node, and a control terminal of the second switch being coupled to the first node;
- a third switch, a first terminal of the third switch being coupled to the second node, a control terminal of the third switch being configured to receive a precharge signal;
- and
- a fourth switch, a first terminal of the fourth switch being coupled to the third node, a control terminal of the fourth switch being configured to receive the precharge signal,
- wherein the fourth switch is turned off when the third switch is turned on.
A method, comprising:
- charging, according to a precharge signal, a first node and a second node corresponding to a first data signal and a second data signal, respectively;
- discharging a third node according to the precharge signal and a reference voltage signal;
- discharging the first node by a first switch coupled between the first node and the third node;
- and
- after the third node is discharged according to the precharge signal, providing the reference voltage signal to the third node to further discharge the first node,
- wherein the first data signal is complementary with the second data signal.
