  • 4DS Memory shares plunged up to 70% on Monday following weak results from its latest technology trial.

  • Initial analysis of the Sixth Platform Lot failed to meet expected electrical performance benchmarks.

  • Company to conduct root cause analysis with industry partners imec and Infineon to address the issue.

4DS Memory Ltd (ASX:4DS) shares suffered a dramatic collapse on Monday, plunging as much as 70% to a low of 1.9 cents in early trade, before slightly recovering. The sharp downturn followed the company's return from a trading halt and the release of a technical update concerning its next-generation memory wafer development.

The sell-off was triggered by a progress report on the company’s Sixth Platform Lot, a critical phase in 4DS’s effort to commercialise its proprietary Interface Switching ReRAM (Resistive Random Access Memory) technology. The company had pinned high hopes on this latest manufacturing batch, intended to showcase its 20-nanometre memory cells, which form the core of its advanced non-volatile memory solution.

4DS Memory, headquartered in Australia, is a semiconductor technology firm focused on developing ReRAM, a high-speed, low-power, and durable memory type aimed at revolutionising data storage. The technology has potential applications in smartphones, data centres, and other high-performance computing environments. 4DS has been working alongside prominent industry players such as imec, Infineon Technologies, and Western Digital to bring this innovation to market.

However, in its Monday update, 4DS revealed that early testing and characterisation of the Sixth Platform Lot have not produced the expected electrical results, despite incorporating lessons and process optimisations from the previous Fifth Platform Lot. The company stated:

“The initial analysis of the wafers within the entire Lot indicates that the necessary process modifications and optimizations introduced into the Sixth Platform Lot have not yielded the expected electrical testing and characterization results the Company was expecting.”

Although testing is still ongoing, the preliminary results raise concerns about whether the wafers are functioning as intended. If final analysis confirms the shortcomings, the outcome would likely cause delays in the development of the company’s core ReRAM product, necessitating further rounds of testing and re-engineering. This, in turn, would mean additional time and resources before a viable commercial product can be introduced to the market.

In response, 4DS confirmed that it is now working with imec and Infineon to conduct a comprehensive root cause analysis of the issue. This collaborative review aims to identify the source of the underperformance and guide the next steps in the company’s development cycle.
