Abstract
A device includes several first switching units and several second switching units. Each of the first switching units transmits in response to a first select signal, an auxiliary signal. Each of the second switching units is coupled to a corresponding one of the first switching units and transmits in response to a second select signal, a write voltage to a corresponding one of multiple circuit cells. The second switching units are coupled with each other in a node which receives the write voltage.
Claims20
A device, comprising:
- a plurality of first switching units each configured to transmit, in response to a first select signal, an auxiliary signal;
- and
- a plurality of second switching units each coupled to a corresponding one of the plurality of first switching units and configured to transmit, in response to a second select signal, a write voltage to a corresponding one of a plurality of circuit cells, wherein the plurality of second switching units are coupled with each other in a node which receives the write voltage.
A method, comprising:
- selectively transmitting, in response to a first select signal, by a first driving branch of a plurality of driving branches a write voltage to an input of a first circuit cell;
- and
- controlling, in response to a control voltage which is generated based on a comparison of a reference voltage and a feedback signal, by the first driving branch, a voltage level of the input of the first circuit cell.
A device, comprising:
- a control signal generator configured to generate a control voltage;
- a first switching unit configured to generate an auxiliary signal in response to the control voltage;
- a second switching unit configured to transmit, in response to a first select signal, the auxiliary signal to a circuit cell;
- and
- a third switching unit configured to transmit, in response to a second select signal, a write voltage to the circuit cell, wherein the circuit cell is programmed according to the auxiliary signal and the write voltage.
