Microchip background


Unbuffered DIMMs are the ideal module for high-speed, low-cost computing systems. Our UDIMMs come in SDRAM, DDR, DDR2, DDR3, and DDR4 solutions and offer data rates as high as 2400 MT/s, and provide parity and ECC capability. They’re an industry standard in high-volume production, offering a great balance of price and performance.
