STORAGE SUBSYSTEM READ VOLTAGE DETERMINATION SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17727716 Titled 'STORAGE SUBSYSTEM READ VOLTAGE DETERMINATION SYSTEM'
Simplified Explanation
The abstract describes a system that determines the optimal read voltage for a storage subsystem. It reads data from the subsystem at different voltage levels and calculates the probability of bit errors for each voltage level. It also generates a graph that shows the error correction capability of the system. Based on these calculations, it determines the average rate of errors for each voltage level and identifies the voltage level with the lowest error rate.
Original Abstract Submitted
A storage subsystem read voltage determination system coupled to a first storage subsystem may read data from the first storage subsystem at a plurality of different read voltage sets and, for each of the plurality of read voltage sets, generate a respective bit error probability distribution of a number of bit errors per codeword provided by the data read from the first storage subsystem. The storage subsystem read voltage provisioning system also generates an error correction capability graph associated with error correction code used by the first storage subsystem and, based on the bit error probability distributions and the error correction capability graph, generates a respective average codeword error rate for each of the plurality of read voltage sets. The storage subsystem read voltage provisioning system then identifies a first read voltage set for which a minimum average codeword error rate was determined.
