Abstract: For a nonvolatile (NV) storage media such as NAND media that is written by a program and program verify operation, the system can determine an expected number of SSPC (selective slow programming convergence) cells for a page of cells for specific conditions of the page. The system can perform program verify with a first wordline (WL) select voltage for SSPC cell detection for a first write of the page to detect the expected number of SSPC cells. Based on the determined expected number of SSPC cells, the system can set a boost voltage to capture an expected number of SSPC cells during the program verify operation. The system performs program verify for subsequent writes to the page with a higher WL select voltage, to perform program verify for standard cells and then SSPC program verify with the boost voltage determined from the first write.

Abstract: A technique is provided for cooling generic many-body quantum systems of unknown Hamiltonians to their ground states with a very high fidelity. The technique works by switching on a strong field and applying a sequence of projective measurements and RF pulses to polarize the system along the direction of the external field before we adiabatically switch the field off. The evolution of the system towards its ground state is governed by the quantum adiabatic theorem. We numerically simulate the proposed technique for quantum spin chains with long and short range interactions.
