Abstract
Various data protection techniques are provided. In one embodiment, a method includes manufacturing a memory component of an electronic system. Manufacturing the memory component may include disposing a memory array on a substrate and coupling a control circuit to the memory array. The control circuit may be configured to selectively prevent access to data stored within the memory array upon removal of the memory component from the electronic system. Various additional methods, devices, and systems are also provided.
Claims22
A method comprising:
- manufacturing a memory component of an electronic system, wherein manufacturing the memory component includes:
- disposing a memory array on a substrate;
- and
- coupling a control circuit to the memory array, wherein the control circuit is configured to selectively prevent access to data stored within the memory array upon removal of the memory component from the electronic system.
1 more element
A method comprising:
- manufacturing a memory component of an electronic system, wherein manufacturing the memory component includes:
- disposing a memory array on a substrate, the memory array including a plurality of wordlines and a plurality of bitlines;
- coupling signal interrupt circuitry to at least one of the plurality of wordlines or the plurality of bitlines, wherein the signal interrupt circuitry is configured to inhibit access to data stored within the memory array upon removal of the memory component from the electronic system.
A method comprising:
- setting an authentication sequence of a data security device, the data security device including a memory and data protection circuitry configured to physically disable access to the memory upon failure of an additional device attempting to access data from the memory to provide the selected authentication sequence to the data security device;
- receiving a signal from the additional device attempting to the access data from the memory;
- determining whether the additional device has provided the selected authentication sequence;
- and
- selectively granting or physically disabling access to the memory, via the data security device, based on the determination of whether the additional device has provided the selected authentication sequence.
2 more elements
A method comprising:
- providing a memory component configured to store data, to sense removal of the memory component from a processor-based system, and to initiate a data security measure, in response to the removal of the memory component from the processor-based system, to inhibit access to data stored within the memory component;
- and
- coupling the memory component to the processor-based system.
