The test program code and limit tables that sort each tested memory part into the bins defined by the bin and grade plan.
Test Work product in the Memory product lifecycle (DRAM, NAND and HBM)
The bin and grade plan only takes effect once it is coded into the test program that runs on production testers. The binning program implements the plan exactly and records each decision. Without a verified program, parts are mis-binned, customers receive parts in the wrong grade and revenue is lost on parts sold below their capability.
