Patent ID: 7706902

Claim:
A listening device comprising: a digital signal processing (DSP) entity for performing real time system processing including audio processing, the DSP entity operating with a first voltage; a non-volatile (NV) memory for communicating with the DSP entity and storing logged data during an operation of the listening device, the NV memory operating with a second voltage different than the first voltage; and a data logging manager for managing data logging to the NV memory during the production of audio to prevent at least one audible side effect associated with the data logging, the data logging manager including: a level translating module coupled with the first voltage and the second voltage for performing voltage level translation to communication signals including a first communication signal transferred from the DSP entity to the NV memory and a second communication signal transferred from the NV memory to the DSP entity; a first voltage regulator coupled to both the DSP and level translating module for providing the first voltage to the DSP and the level translating module; and a second voltage regulator coupled to a charge pump for providing the second voltage, the charge pump coupled to the level translating module for providing the second voltage to the level translating module.
