Abstract
The present disclosure includes apparatuses and methods related to a sense amp balancing component in memory. An example apparatus can include a sense amp connected to a first digit line and a second digit line, and a controller configured to: send a first activation signal to the first digit line at a first time during a compensation window, and send a second activation signal to the second digit line at a second time during the compensation window, wherein the first time and the second time have a time difference that corresponds to a threshold voltage difference between the first digit line and the second digit line.
Claims20
An apparatus, comprising:
- a sense amp connected to a first digit line and a second digit line;
- and
- a controller configured to:
- apply a first activation signal to the first digit line at a first time during a compensation window associated with a sensing operation;
- and
- apply a second activation signal to the second digit line at a second time during the compensation window, wherein the first time and the second time have a time difference that corresponds to a threshold voltage difference between the first digit line and the second digit line.
An apparatus, comprising:
- a sense amp connected to a first digit line and a second digit line;
- a first isolation device connected to the first digit line and configured to, in association with a sensing operation, receive a first activation signal at a first voltage;
- and
- a second isolation device connected to the second digit line and configured to, in association with the sensing operation, receive a second activation signal at a second voltage;
- wherein the first voltage is greater than the second voltage to provide a balancing effect for the sense amplifier by increasing a voltage on the first digit line as compared to the second digit line.
A method, comprising:
- providing, by a controller, a first activation signal to a first digit line of a sense amp at a first time during a compensation window of the sense amp;
- providing, by the controller, a second activation signal to a second digit line of the sense amp at a second time during the compensation window of the sense amp, wherein the first time and the second time have a time difference that corresponds to a first threshold voltage difference between the first digit line and the second digit line;
- providing, by a first isolation device connected to the first digit line, a first voltage to the first digit line in response to an activation of the sense amp;
- and
- providing, by a second isolation device connected to the second digit line, a second voltage to the second digit line in response to the activation of the sense amp, wherein the first voltage is greater than the second voltage by a second threshold voltage difference.
