64k-DRAM-1979 Step 16 Scale Burn in and Test Equipment to 64k Volume

# Scale Test and Burn-In Equipment to Match 64K-Era Production Volume

Step 12 measured soft-error rates through accelerated testing; a broader test-and-burn-in infrastructure question applies to this entire generation's manufacturing volume, worth naming on its own terms.

## 1. State the Volume Problem Test Equipment Had to Solve

This generation's manufacturing volume, driven by the commercial race Step 7 named among Mostek, Texas Instruments, and the named Japanese manufacturers, required functional testing — verifying every cell's write, read, and refresh behavior (this project's `dram_1968` series own Steps 1-9 physics, now checked per manufactured part rather than derived in the abstract) — and burn-in screening (accelerated operation under elevated voltage and temperature to filter latent defects before shipment) at a throughput test equipment from earlier, lower-volume memory generations could not sustain.

## 2. Trace the Equipment Response

Automated test equipment capable of exercising a part's full RAS/CAS/refresh sequence (Steps 2, 4, 5, 9, 11) at speed, across many parts in parallel, replaced the slower manual or semi-automated test fixtures adequate for earlier, lower-capacity, lower-volume memory parts. This mirrors the test-and-measurement equipment scaling this project's Mesa Production (1958) series names explicitly (its own Step 19) for a much earlier transistor generation, facing the identical structural problem — test throughput becoming the production bottleneck if it does not scale alongside volume.

## 3. Connect Test Scaling to the Generation's Commercial Outcome

A manufacturer whose test and burn-in infrastructure could not keep pace with its own fabrication volume effectively forfeited the cost advantage its fabrication capacity should have delivered — test throughput, not wafer output alone, determined how much of this generation's manufactured capacity could actually reach customers at an acceptable, verified quality level.
