Abstract
Apparatuses and methods for adjusting deactivation voltages are described herein. An example apparatus may include a voltage control circuit. The voltage control circuit may be configured to receive an address and to adjust a deactivation voltage of an access line associated with a target group of memory cells from a first voltage to a second voltage based, at least in part, on the address. In some examples, the first voltage may be lower than the second voltage.
Claims28
An apparatus, comprising:
- a voltage control circuit configured to receive an address and adjust a deactivation voltage of an access line associated with a target group of memory cells from a first voltage to a second voltage based, at least in part, on the address,
- wherein the first voltage is a lower voltage than the second voltage.
An apparatus, comprising:
- an access line associated with a target group of memory cells;
- a voltage control circuit coupled to each of a plurality of drivers and configured to provide a first deactivation voltage to a first set of the plurality of drivers and to provide a second deactivation voltage to a second set of the plurality of drivers,
- wherein the second deactivation voltage is lower than the first deactivation voltage and wherein one of the first set of the plurality of drivers is coupled to the access line associated with the target group of memory cells.
An apparatus, comprising:
- a first plurality of drivers coupled to a first plurality of access lines respectively;
- a second plurality of drivers coupled to a second plurality of access lines respectively;
- a voltage control circuit coupled to the first plurality of drivers by a first bus and coupled to the second plurality of drivers by a second bus, the voltage control circuit configured to provide a first deactivation voltage to the first and second pluralities of drivers, the voltage control circuit further configured to adjust the deactivation voltage of the first plurality of drivers from the first deactivation voltage to a second deactivation voltage based, at least in part, on an address associated with an access line of the first plurality of access lines.
A method, comprising:
- providing, with a driver, a first voltage to an access line for a first portion of a memory operation;
- providing, with the driver, a second voltage to the access line for a second portion of the memory operation;
- providing, with the driver, a third voltage to the access line for a third portion of the memory operation, the first voltage lower than the third voltage, the first and third voltages comprising deactivation voltages and the second voltage comprising an activation voltage.
A method, comprising:
- during a memory operation, adjusting the deactivation voltage of a first plurality of access lines from a first voltage to a second voltage;
- and
- during the memory operation, maintaining the deactivation voltage of a second plurality of access lines at the first voltage.
