Serial PCM for Design Simplicity

Our phase change memory (PCM) combines the best traits of traditional memory technologies into a single, nonvolatile device with a straightforward serial interface. Ideal for high-density SPI architectures, P5Q products simplify design, improve system performance, and extend the capabilities of a wide variety of applications.

tunnelSerial Solutions for Today and Beyond

Is there a single memory technology that can fit all your embedded application needs, with the design simplicity and drop-in convenience of a serial interface? Yes.

The P5Q PCM is purpose-built to meet the memory requirements of embedded systems, delivering multiple I/O capability and compatibility via familiar SPI NOR interfaces. P5Q improves overall performance and enables software simplification using byte-alterability (overwrite capability). It also increases system-level reliability by delivering 1 million write-cycle endurance (compared to 100,000 for NOR flash).
