For a stock at 28 times forward earnings guiding December-quarter growth near 130%, that constraint is the one to price. ## The sell-off priced Nvidia; the constraint that binds is memory [Lattice Semiconductor](https://theinference.org/markets/companies/lattice-semiconductor) fell 5.4% on November 12, 2026, the day [Jensen Huang](https://theinference.org/markets/people/jensen-huang) resigned as [Nvidia](https://theinference.org/markets/companies/nvidia)'s chief executive [1]. It fell again on November 13, closing down 5.47% on the market's heaviest turnover of the day, as October wholesale inflation lifted long-term yields [2][3]. The tape priced sector news. It has not priced what Lattice's own Asia-Pacific president, Xu Honglai, [told the China Import Expo on November 13](https://www.icgoodfind.com/cms/Article/get/article_id/19342): data-center customers must have CPUs, HBM and DDR memory together in a rack, and when one is missing, system procurement and delivery are delayed [4]. Lattice cannot control DDR capacity, he said [4]. The same day, [Intel](https://theinference.org/markets/companies/intel)'s chief executive [Lip-Bu Tan](https://theinference.org/markets/people/lip-bu-tan) said memory prices have risen "six, seven times", that buyers willing to pay may still get nothing, and that 2027 could be worse [5]. ## The chips ship out on racks, and racks do not close without DDR Lattice sells small, low-power field-programmable gate arrays, chips whose wiring customers configure after manufacture, that sit beside the big processors in AI servers: they sequence power-on, run thermal management and catch liquid-cooling leaks [4]. Since the AMI acquisition closed in July, they come with firmware that boots and manages whole GPU racks, a climb from board-level control to rack management that is the real work of making AI infrastructure operable [6]. Chief executive [Ford Tamer](https://theinference.org/markets/people/ford-tamer) says FPGA content per server has gone from one or two chips to three and now "starts with a four" [7]. ## The guide is booked; the last hop is not Lattice's to control [Revenue was $291 million in the September quarter](https://finance.yahoo.com/technology/articles/lattice-semiconductor-reports-record-3q26-210000005.html), more than double a year earlier, and the FPGA business alone grew about 90% without AMI's help [6]. The December quarter is guided up about 130% [6]. *Chart: **Revenue doubled in a year, and December is guided to double again** Column chart of Lattice Semiconductor quarterly revenue from Q4 2024 through Q3 2026, with Q4 2026 guidance marked as an estimate.* *Quarterly revenue in US$ millions; Q4 '26 is the guidance midpoint of a $325–345 million range. Sources: Lattice SEC filings; Q3 2026 press release. [6][8]* Every one of those chips is booked when its board ships into a rack. Lattice's own wafer supply is locked on multiyear agreements and its backlog runs into 2028 [7]. The customer's DDR line is the one hop Lattice cannot see, and its guidance now runs through that hop [4][5]. ## Watch memory lead times, not Lattice's order book Demand is the observable half of this chain: bookings, backlog into 2028, content per rack rising, and a management team [guiding to at least 60% growth in 2027](https://finance.yahoo.com/technology/articles/lattice-semiconductor-lscc-said-q3-011406208.html) [7]. Assembly is the projection. [Micron](https://theinference.org/markets/companies/micron) has already sold the vast majority of its calendar 2027 high-bandwidth memory at higher prices, so what memory exists goes first to whoever prepaid [5]. If DDR stays scarce, deliveries slide right rather than demand disappearing, and a stock at 28 times forward earnings, with $18.4 million of net insider selling over the past year, carries timing risk the multiple does not show [9]. Lattice's 2027 will be decided in memory allocation meetings it does not attend. The build-out is real, and the climb from control chips to rack managers deserves the reward it is earning [6]. The calendar for that reward now belongs to the memory makers. ## Takeaway Lattice has the December quarter booked. Whether it ships on time depends on DDR memory the company does not control. ## Sources 1.
