 note = {In nanoscale metrology, dissipation of the sensor limits its performance. Strong dissipation　has a negative impact on sensitivity, and sensor–target interaction even causes relaxation or　dephasing of the latter. The weak dissipation of nitrogen-vacancy (NV) sensors in room　temperature diamond enables detection of individual target nuclear spins, yet limits the　spectral resolution of nuclear magnetic resonance (NMR) spectroscopy to several hundred　Hertz, which typically prevents molecular recognition. Here, we use the NV intrinsic nuclear　spin as a nonvolatile classical memory to store NMR information, while suppressing sensor　back-action on the target using controlled decoupling of sensor, memory, and target. We　demonstrate memory lifetimes up to 4 min and apply measurement and decoupling protocols,　which exploit such memories efficiently. Our universal NV-based sensor device records　single-spin NMR spectra with 13 Hz resolution at room temperature.},
