The read threshold voltage can be adjusted by reading the memory at a current read threshold voltage to obtain a read value; applying a hard decision decoder to the read value; determining if the hard decision decoder converges for the read value to a converged word; storing bits corresponding to the converged word as reference bits and, if the hard decision decoder converges, (i) computing a bit error rate for the current read threshold voltage based on the reference bits; (ii) adjusting the current read reference voltage to a new read threshold voltage; and (iii) reading the memory at the new read threshold voltage to obtain a new read value, until a threshold is satisfied; and once the threshold is satisfied, selecting the read threshold voltage based on the bit error rates."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Read threshold voltage adaptation using bit error rates based on decoded data","description":"A read threshold voltage for a memory is adjusted based on a bit error rate based on decoded data for a plurality of read threshold voltages.
