Abstract
Apparatuses and methods related to updating data lines for data generation in, for example, a memory device or a computing system that includes a memory device. Updating data lines can include updating a plurality of data lines. The plurality of data lines can provide data form the memory array responsive to a receipt of the access command. The plurality of data lines can also be updated responsive to a determination that an access command received at a memory device is unauthorized.
Claims20
An apparatus, comprising:
- a memory array;
- sensing circuitry;
- control circuitry coupled to the memory array and the sensing circuitry and configured to:
- receive an access command targeting a particular address within the memory array;
- responsive to determining that the received access command is not authorized to access the particular address, update a plurality of data lines configured to provide data from the memory array responsive to receipt of access commands,
- wherein the plurality of data lines coupled to the sensing circuitry are updated by resetting a plurality of keeper latches coupled to the plurality of data lines to update the plurality of data lines.
3 more elements
An apparatus, comprising:
- a memory array;
- sensing circuitry;
- a plurality of latches, wherein each of the plurality of latches comprises a plurality of AND gates and a plurality of NOR gates;
- and
- control circuitry coupled to the memory array and the sensing circuitry and configured to:
- receive an access command targeting a particular address within the memory array;
- responsive to determining that the received access command is not authorized to access the particular address, update a plurality of data lines configured to provide data from the memory array responsive to receipt of access commands,
- wherein the plurality of data lines coupled to the sensing circuitry are updated by resetting a plurality of latches coupled to the plurality of data lines to update the plurality of data lines.
5 more elements
A method, comprising:
- receiving an access command targeting a particular address within a memory array;
- determining that the received access command is not authorized to access the particular address;
- responsive to determining that the received access command is not authorized to access the particular address, updating a plurality of data lines configured to provide data from the memory array responsive to receipt of access commands;
- wherein the plurality of data lines are updated by resetting a plurality of latches coupled to the plurality of data lines to update the plurality of data lines;
- and
- wherein the plurality of latches comprise a first AND gate, a second AND gate, a first NOR gate, and a second NOR gate.
