MRAM Strengthens Kingston’s Role in Cardiac Monitoring and Supply Chain Logistics

This article describes Ambiq’s announcement of an open-source AI model for cardiac monitoring applications running on Apollo4 Plus chips with MRAM and other memories. We also examine the role Kingston Technology plays in managing excess memory inventories for suppliers and customers.

Wearable AI chip maker Ambiq has unveiled open-source AI models powered by multi-head neural networks (MH-NN), enabling a variety of real-time cardiac monitoring applications running on its Apollo4 Plus chip. bottom. It’s called HeartKit and is currently available as a technical preview at the link below.

HeartKit includes scripts and tools to help AI developers add real-time ECG monitoring capabilities to their healthtech applications. The image below shows the features shown in the HeartKit Demo.

The Apollo4 Plus SoC offers three types of memory used for AI: MRAM, Tightly-Coupled Memory (TCM), and SSRAM. MRAM is a highly efficient non-volatile memory primarily for storing static values. TCM, as the name suggests, is a high performance read/write memory that is tightly coupled to the CPU. SSRAM is general purpose read/write memory “further” from the CPU. MRAM offers superior performance and energy efficiency when combined with TCM or SSRAM.

Using non-volatile MRAM memory to complement SRAM and energy-efficient algorithms allows the company to deliver 13x higher AI efficiency. The chart below compares Apollo4 Plus to other AI inference engines for some tasks, showing that Apollo4 Plus runs many AI applications at much lower power.

This superior power efficiency allows the Apollo4 chip to run the same applications with longer battery life, deliver better endpoint AI applications with the same battery life, and enable new endpoint applications where power is not a big issue. .

Kingston Technology claims to have shipped over 100 million overclocked memory modules. In March, Kingston added Kingston FURY Renegade Pro DDR5 RDIMMs to its product line. It offers creators, engineers, and data science professionals his DDR5 memory of overclockable server class. In addition, Kingston FURY Beast DDR5 and Renegade DDR5 memory modules have also been revamped, introducing a white heat spreader and allowing users to choose the color that best suits their individual style.

Kingston Senior Technology Manager Mike Mohney recently had the opportunity to speak with him about the role his company plays in the memory and storage industry. Kingston, in particular, acts as a bridge between major semiconductor suppliers. They not only offer branded products through channels of branded computers, but also white box solutions and products for gaming. However, most of their business is related to contract manufacturing and supply chain logistics for top server and hyperscale data center customers.

This last feature, Supply Chain Logistics, may require some explanation. Kingston has long-term agreements (LTAs) with suppliers and is a major seller in channel and client markets, so Big His Memory helps his suppliers sell off their surplus inventory. We are now removing memory inventory from our large customer inventory and reselling these products through our channel. This improves the financial situation of our customers and also creates value for our suppliers, so we tend to continue supplying Kingston with memory products when the market improves.

Ambiq’s Apollo4 Plus chip uses MRAM to enable low-power cardiac monitoring. Kingston Technology has helped suppliers and customers deal with excessive memory inventory, selling over 100 million overclocked memory modules.
