Methods, systems, and devices for turbo redundant array of independent not-and (RAIN) operations across planes of a memory system are described. A memory system may perform a turbo RAIN recovery procedure to correct multiple uncorrectable errors in a page stripe of the memory system. As part of the turbo RAIN recovery procedure, the memory system may calculate a reference value based on a combination of good data within the page stripe. The calculation of the reference value may be the same irrespective of which error of the multiple uncorrectable errors is being corrected, and the memory system may store the calculated reference value for a duration until the multiple uncorrectable errors of the page stripe are corrected. For each error that is corrected, the memory system may fetch the stored reference value for performing error correction.
