Thank you, and good afternoon, everyone. Welcome to the Lam Research quarterly earnings conference call. With me today are Tim Archer, president and chief executive officer; and Doug Bettinger, executive vice president and chief financial officer. During today's call, we'll share our overview on the business environment, and we'll review our financial results for the December 2021 quarter and our outlook for the March 2022 quarter.
The press release detailing our financial results was distributed a little after 1:00 p.m. Pacific Time this afternoon. The release can also be found on the Investor Relations section of the company's website, along with the presentation slides that accompany today's call. Today's presentation and Q&A include forward-looking statements that are subject to risks and uncertainties reflected in the risk factors disclosed in our SEC public filings.

A detailed reconciliation between GAAP and non-GAAP results can be found in the accompanying slides in the presentation. This call is scheduled to last until 3:00 p.m.
Pacific Time. A replay of this call will be made available later this afternoon on our website. And with that, I'll hand the call over to Tim.
Tim Archer -- President and Chief Executive Officer
Thank you, Tina, and happy new year to all that are joining us today. Calendar 2021 was another year in which companies and our communities had to respond to significant challenges on many fronts. Lam's operations and results were impacted by the effects of COVID-19, labor shortages, freight and logistics cost escalation, and supply chain constraints. But I am proud and thankful for how Lam employees responded at every turn, with commitment and agility to support our customers and business.
As the digital transformation of both the global economy and our everyday activities accelerated throughout the year, demand for wafer fabrication equipment continued to strengthen. Lam delivered record revenues and record earnings per share in calendar year 2021. Embedded in these results is record revenue in every area of our business, including NAND, DRAM, and Foundry/Logic, and within every subsegment of our customer support business. Even in a year with relatively higher Foundry/Logic spend versus Memory, we gained market share in both etch and deposition.
