Phase Change Memory Size

The global phase change memory market was valued at USD 564.7 million in 2024. The market is expected to grow from USD 709 million in 2025 to USD 6.18 billion in 2034, at a CAGR of 27.2% during the forecast period according to the latest report published by Global Market Insights Inc.

The PCM market is gaining traction as demand builds for high speed, non volatile memory solutions that combine DRAM class performance with flash class persistence. These memories are increasingly required in AI, big-data and edge systems where throughput, energy efficiency and data retention are critical.

The transition toward architecture designs that embed larger, faster non volatile memory blocks on chip or near processor is accelerating PCM’s role in future memory hierarchies. For instance, STMicroelectronics describes its embedded PCM (ePCM) technology as offering “>50% better performance to power ratio, 2.5× smaller non volatile memory, 3× higher digital density” compared to conventional flash based eNVM at equivalent node size. This driver is fuelling the adoption of PCM by enabling richer firmware, AI/ML code-footprint, and persistent caching or in memory compute capabilities, increasing the demand for high-performance, on-chip memory solutions.

Industries such as automotive electronics, electric vehicles (EVs) and autonomous systems are rapidly adopting advanced memory technologies to support over the air (OTA) updates, complex domain controllers, sensor fusion, and real-time data logging. PCM is particularly well suited because of its retention, high temperature tolerance and embedded non-volatile character. For instance, STMicroelectronics’ automotive MCU portfolio with embedded PCM (the “Stellar” family) is described as delivering scalable memory upgrades and future proofing vehicles’ electronic architectures.

This driver is accelerating PCM integration in premium automotive microcontrollers and domain controllers, increasing per unit memory content and generating higher-value deployments.

PCM’s role is also expanding through integration into hybrid memory architectures and storage class memory solutions bridging the gap between DRAM and NAND, offering persistent memory closer to the processor, and enabling new system level architectures for AI, edge and cloud systems. For instance, Rambus, Inc. in collaboration with IBM Corporation announced hybrid memory system architectures combining DRAM and emerging memories including PCM for future highly memory intensive AI and data-center workloads.

This trend is expanding PCM’s application in multi tier memory hierarchies, driving demand in hybrid modules, storage class memory, and persistent memory markets. Recent advancements in materials engineering, cell architecture, 3D/stacked PCM cell technologies and process node scaling are accelerating PCM’s performance, density, and energy efficiency. These innovations are making PCM more viable for high-volume applications.

For instance, STMicroelectronics states that their ePCM at 18 nm and 28 nm nodes enables high temperature retention, radiation hardening, automotive grade qualification and operation up to +165-°C. Such technological advancements are broadening PCM’s reach into previously inaccessible markets such as automotive, ruggedized industrial, & edge computing, boosting adoption & scaling deployment volumes.

A further trend is ongoing material engineering and 3D/stacked cell technologies for PCM innovations in chalcogenide alloys, nanostructuring, vertical stacking and advanced packaging are driving higher densities, lower energy per bit and improved scalability. For instance, research shows that interfacial thermal resistance management in ultra thin phase change layers can reduce reset energy by ~40 50%. These improvements make PCM more commercially viable for mass applications beyond niche segments.
  
• As these technologies mature, cost per bit falls, enabling PCM to compete with mainstream memory types in volume markets and opening new application spaces in consumer electronics and edge devices. The PCM market is also experiencing a trend of increasing deployment in AI, big data and edge systems that demand high speed, non volatile memory with low latency and high endurance. For example, PCM is being referenced as a candidate for “persistent memory” in high performance computing, hybrid compute storage modules and in memory compute.
  
• By enabling near DRAM speed with non volatility, PCM supports real time analytics, local AI inference and edge processing, thus significantly expanding its market potential. By aligning with edge infrastructures and data intensive workloads, this trend is enlarging PCM’s addressable market and positioning it as a key enabler in future computing architectures.
  
• There is a trend to low-power, always-on memory in the fields of IoT and consumer electronics, with advantages of PCM's non-volatility, high endurance and low standby power, compared to normal memory options. For instance, some PCM technology road maps highlight extremely low energy per bit operation and better retention, making it well suited for wearable, sensor node and smart device platforms.
