In general, a three dimensional microphone and a three dimensional hearing aid is described. An elongated resilient skin contacting element is joined to the proximal end portion of the housing. The MFS is located between the cladding element and the MTJ. Then the values from the Read Pointer counters RP_i are individually offset by corresponding amounts to compensate for the misalignment, so that when data is read it is indeed aligned. The first half of the 4T compare circuit is positioned so that is extends between the first pair of access transistors and the first pair of cross-coupled inverters.
