Proactive history read adaptation without test read

A memory system, comprising:

• a memory;
• a controller coupled to the memory and configured to read data from the memory, wherein the controller is configured to:
• perform read operations on the memory while recording as read retry (RR) biases a set of history entries of voltages used to read the memory;
• select from the set of history entries the RR biases for subsequent read operations of the memory without performing a test operation with any of the RR biases before the subsequent read operations;
• in the subsequent read operations, read the memory with one or more of the RR biases from the history entries;
• when a failed bit count is higher than a threshold for the subsequent read operations, evict a worst entry based on the failed bit count from the history entries and introduce a new history entry into the set of history entries;
• and
• update the RR biases based on the new history entry.
