20120233384 | METHODS AND SYSTEM FOR ERASING DATA STORED IN NONVOLATILE MEMORY IN LOW POWER APPLICATIONS - The erasing of data stored in a nonvolatile memory is performed using multiple partial erase operations. Each partial erase operation has a time duration that is shorter than the minimum time duration of an erase operation that is needed to reliably erase the data stored in the storage location. However, the sum of the time durations of the multiple partial erase operations is sufficient to reliably erase the data in the storage location. In one example, during a partial erase operation, a voltage is applied to a memory storage transistor to remove some, but not necessarily all, of the charge stored on a charge storage layer of the transistor. Following multiple partial erase operations, sufficient charge is removed from the charge storage layer to ensure reliable data erasure. | 09-13-2012 |
20150050926 | LOW POWER TIMING, CONFIGURING, AND SCHEDULING - A device reduces its energy consumption using a relatively lower frequency and lower power secondary oscillator to maintain timing information when a higher frequency and higher power primary oscillator is inactivated. The secondary oscillator maintains timing information at a higher resolution than the period of the oscillator, so as to conserve synchronization when the higher frequency, higher power primary oscillator is inactivated. In some embodiments, a microsequencer is programmably configured to control an integrated radio receiver and transmitter using less power than an associated microprocessor would use to perform the same functions. In other embodiments, flexible event timing facilitates the merging of wake-up events to reduce the energy consumed by wake-up operations in the device. | 02-19-2015 |
