20130242682 | MEMORY DEVICE POWER CONTROL - The apparatus described herein may comprise a first set of transistors, including a first transistor and a second transistor, and a second set of transistors, including a third transistor and a fourth transistor. Gates of the first and second transistors may be coupled to a first signal and a second signal, respectively, each indicating whether a corresponding one of a first supply voltage and a second supply voltage reaches a first threshold voltage or a second threshold voltage to power on a first circuit or a second circuit of a memory device. Gates of the third and fourth transistors may be coupled to a first inverted version of the first signal and a second inverted version of the second signal, respectively. An outcome signal of the second set of transistors may indicate a power-on state of the memory device responsive to power states of the first and second signals. | 09-19-2013 |
20140098623 | APPARATUSES AND METHODS FOR SENSING FUSE STATES - Apparatuses and methods for sensing fuse states are disclosed herein. An apparatus may include an array having a plurality of sense lines. A plurality of cells may be coupled to a sense line of the plurality of sense lines.
