Intel laid off 15,000 workers last year and is preparing for another round of cuts next month, OregonLive reports, citing an internal memo. Intel Foundry head Naga Chandrasekaran informed employees about the job cuts on Saturday.

That reduction will soon result in sizable layoffs at Intel Foundry, according to The Oregonian. The report is based on an email sent to Intel employees. Although Intel hasn’t confirmed the memo, multiple Intel employees confirmed it to the publication.

Intel is reportedly planning to lay off 20% of its factory workers amid faltering demand for its core products.
