Over the past several months, the semiconductor industry has been experiencing significant supply-chain challenges, especially when it comes to sourcing SLC (Single-Level Cell) NAND memory and related components. These shortages are affecting manufacturers across the world, and unfortunately, we are not immune to these constraints.
Despite these challenges, we want to reassure you of one thing:
We remain fully committed to supporting our customers and sustaining supply for as long as possible.
Below is an inside look at what’s happening in the market, how it impacts SLC memory products, and — most importantly — the steps we’re taking to ensure continuity for you.
Why SLC Components Are in Short Supply
Although many parts of the semiconductor supply chain have seen disruptions over the last few years, the situation for SLC NAND is particularly challenging. A few key factors are driving the shortage:
1. Limited manufacturing capacity for legacy nodes
SLC NAND is produced on older manufacturing processes that many large fabs are gradually phasing out in favor of newer, high-density technologies like TLC/QLC NAND and HBM. As a result, fewer wafers are allocated for low-volume SLC production.
2. Sharp increases in global demand
Industries such as automotive, industrial automation, and critical embedded systems — which rely heavily on SLC for its endurance and reliability — have all seen rapid growth. Demand is now outpacing available supply.
3. Supply constraints in supporting components
Even when wafers are available, related parts such as controllers, substrates, and specialized packaging materials have become harder to obtain, creating additional bottlenecks.
How This Affects Production and Lead Times
Because of these global shortages:
- Lead times for SLC memory components have increased.
- Some suppliers are enforcing strict allocation or minimum order quantities.
- Costs for certain parts have risen sharply as demand exceeds supply.
That said, we want to emphasize that we are still shipping SLC-based products — just with tighter constraints than in previous years.
How We’re Supporting You Through the Shortage
Despite the challenges, we’re taking proactive steps to continue serving our customers at the highest possible level:
1. Securing multiple sources where available
We are working with a broader set of suppliers and distributors to diversify our component options. This helps us maintain steady supply even when individual vendors face disruptions.
2. Increasing forward-ordering and inventory buffers
To reduce future risk, we’ve expanded our procurement window and increased inventory commitments with key partners — even before we receive customer purchase orders.
3. Prioritizing long-term and mission-critical customers
For customers with ongoing programs, long product lifecycles, or mission-critical reliability requirements, we are actively setting aside dedicated allocations to prevent service interruptions.
4. Offering drop-in alternatives where appropriate
In some applications, we may be able to offer compatible memory options that maintain performance, endurance, and reliability.
5. Maintaining full transparency
Most importantly, we will continue communicating clearly about availability, lead times, and any changes that might affect your planning. We believe transparency builds trust — especially when the industry is in flux.
What You Can Do to Help Us Support You
We encourage our customers to take the following steps to avoid delays:
- Place orders as early as possible, especially for recurring or long-term programs.
- Share projected demand or forecasts, even if approximate, so we can plan supply accordingly.
- Discuss alternatives or stocking strategies with our team if your application allows flexibility.
Early communication makes a significant difference in our ability to secure components on your behalf.
We’re Here for You — Even in a Challenging Market
The supply chain environment may be unpredictable, but our commitment to our customers is not.
We understand that many of you rely on SLC-based products for industrial, embedded, and high-reliability applications where alternatives are not always acceptable. We take that responsibility seriously, and we are doing everything possible to ensure continued availability and support.
If you have questions about lead times, product options, or future planning, please reach out to our sales or support team. We’re here to help you navigate this period and keep your projects running smoothly.
