GSI Technology (GSIT) has a supply chain with one disclosed wafer supplier: Taiwan Semiconductor Manufacturing Company (TSM) supplied every wafer used in GSI’s SRAM products for each of the last three fiscal years. The company also sells through, and directly to, Cadence Design Systems (CDNS), giving Cadence multiple roles in the map.

That TSMC relationship is unusually explicit. GSI does not describe a roster of wafer foundries, or even a primary supplier. It names one.

"During the years ended March 31, 2026, 2025 and 2024, all of the wafers used in the Company’s SRAM products were supplied by Taiwan Semiconductor Manufacturing Company Limited, or TSMC."

In plain English, all disclosed SRAM wafer sourcing ran through TSMC across those three years. The filing does not quantify how much of GSI’s total business is SRAM, but it does give the supplier relationship a clear boundary for SRAM wafer sourcing.

Cadence occupies a stranger spot. GSI names it as an OEM customer, and separately reports that direct and indirect sales to Cadence rose from $1.6 million to $3.1 million in fiscal 2026. Cadence also purchases GSI products through contract manufacturers and distributors.

"We maintain long-term relationships with leading original equipment manufacturer (“OEM ”) customers, including KYEC, Cadence Design Systems, and Nokia."

Cadence is therefore disclosed on the customer side of the ledger, alongside Nokia (NOK), and as part of the route by which products reach buyers. The same company appears in multiple lanes, which is more complicated than a simple supplier-to-customer diagram.

"Direct and indirect sales to Cadence Design Systems increased by $1.5 million from $1.6 million in fiscal 2025 to $3.1 million in fiscal 2026."

The disclosed sales increase is concrete. It also makes Cadence the only relationship in the supplied filings that is described both by role and by a year-over-year dollar change.

GSI’s US distribution network includes Avnet (AVT). The company says its relationship with US distributors helps it address the Very Fast SRAM market, while separately noting that distributors can choose to spend more marketing resources on other companies’ products.

"We believe that our relationship with our U.S. distributors, Avnet, Mouser and Digi-Key, put us in a strong position to continue to address the Very Fast SRAM memory market in the United States."

GSI Technology, Form 10-K, filed June 5, 2026

That is the disclosed distribution structure: Avnet is named as a distributor, and Avnet Logistics is also described as a partner whose marketing attention may also go to other companies’ products.

On the customer side, GSI’s representative OEM list for fiscal 2025 included Lockheed Martin (LMT). Its fiscal 2026 list included General Dynamics (GD), alongside Cadence and other aerospace and industrial names. Nokia appears in the company’s long-term OEM relationships, giving the customer map a distinctly hardware-and-defense flavor.

"Our principal competitors include NVIDIA Corporation and Intel Corporation for our in-place associative computing solutions and Infineon Technologies AG , Integrated Silicon Solution and Renesas Electronics Corporation for our SRAM products."

GSI Technology, Form 10-K, filed June 18, 2025

The competitive map splits in two: NVIDIA (NVDA) and Intel (INTC) are named against GSI’s in-place associative computing solutions, while Infineon (IFNNY), Integrated Silicon Solution, and Renesas are named against SRAM. GSI also says it acquired substantially all assets related to Sony’s (SONY) SRAM memory device line in 2009. Its disclosed ties are not one neat chain. They are one wafer source, one unusually multifunctional customer, a distributor network, and competitors sorted by product line.
