Samsung Electronics

Samsung Electronics established January 13 in Suwon, South Korea as a consumer-electronics arm of the Samsung Group, initially producing black-and-white TVs and white goods before pivoting toward semiconductors in the late 1970s.

Founder Lee Byung-chul announced the 'Tokyo Declaration' committing Samsung to enter the DRAM business despite warnings of certain failure; the strategic bet would reshape global memory markets within a decade.

Shipped first Samsung-designed 64Kb DRAM, completing the chip in just six months; technology was reverse-engineered with help from Micron Technology under a license deal.

Demonstrated 1Mb DRAM, closing the gap to US/Japanese leaders to roughly six months; commercial production began 1987 ahead of the 1988 industry inflection.

Surpassed Toshiba and Hitachi to become world’s largest DRAM supplier; Samsung’s memory leadership has held continuously for 33+ years through 2026.

Launched Samsung Foundry business under the System LSI division to compete directly with TSMC; first major customer win was Apple's A4 SoC in 2010 for the original iPad.

Apple A4 SoC for the iPad debuted on Samsung's 45nm process; the design win cemented Samsung Foundry's leading-edge credibility ahead of TSMC for several years.

Apple sued Samsung over patent infringement, kicking off a five-year legal war; despite the dispute, Apple kept Samsung as foundry partner and DRAM supplier through 2013.

Began industry-first volume production of 3D V-NAND flash memory; the vertical stacking architecture solved the 2D NAND scaling wall and gave Samsung a multi-year NAND lead.

Began 14nm FinFET production December, first to volume on FinFET ahead of TSMC by months; won Apple A9 and Snapdragon 820 fabrication on the back of the lead.

Won Apple A9 fabrication on its 14nm FinFET process alongside TSMC's 16nm; though Apple controversially returned to TSMC-only for A10, Samsung retained Snapdragon flagships through 2018.

Announced $17B Taylor, Texas fab in November 2021 (publicly disclosed late August internally); the largest foreign direct investment in Texas history, targeted for 4nm/2nm production.

First foundry to mass-produce 3nm with Gate-All-Around (MBCFET) architecture, beating TSMC to GAA by two years; yields lagged TSMC, however, costing Samsung Foundry market share.

Received one-year US license waiver to keep importing chip-making equipment for its Xian NAND fab; the temporary reprieve later became indefinite Validated End User status in October 2023.

Granted indefinite Validated End User status by US, easing equipment shipments to its China memory fabs; removed annual license-renewal cliff that had caused FY23 capex hesitation.

Awarded preliminary $6.4B CHIPS Act funding for Taylor, Texas leading-edge fab and packaging facilities; total Samsung US commitment grew to ~$45B over the decade.

Foundry losses widened past $3B for FY2023 as 3nm GAA yields lagged TSMC, prompting executive shake-up; Samsung lost Qualcomm Snapdragon 8 Gen 4 and Tesla AI5 to TSMC.

Issued rare apology over weak HBM3e qualification at NVIDIA, conceding lost ground to SK Hynix and Micron; chairman vowed to overhaul DS Division leadership and yield engineering.

Final CHIPS Act award cut to $4.75B from preliminary $6.4B as Taylor expansion plans were trimmed; reflected Samsung Foundry's customer-win struggles vs TSMC.

December 2 BIS rules extended HBM export controls country-wide, hitting Samsung's China memory revenue stream; Huawei Ascend AI chip ramp directly impacted.

Qualified HBM3e 12-layer at NVIDIA after months of yield rework, partially recovering AI memory share; allocation gain estimated at 5-8% of 2025 HBM3e shipments.

Delivered paid HBM4 samples to NVIDIA, regaining a foothold in the AI memory supply chain after HBM3 stumbles; targeted ~28% HBM4 share alongside SK Hynix and Micron.
