Dynamic Random Access Memory (DRAM) Patents
DRAM is the most commonly used type of computer memory in the world, with DRAM semiconductor technology found in most computerized devices. MOSAID’s reputation as a technology innovator was established in the mid-1970s, when our engineers made important discoveries that significantly improved the operation of DRAM semiconductor chips. We invented novel approaches to wordline driver and bitline isolation techniques, Delay Locked Loop (DLLs), sense amplifiers and memory array architecture.

Many of these innovations were widely adopted in the DRAM industry, leading to our first patent licensing program. We signed our first patent licensing agreement in 1999. Today, we’ve successfully now licensed virtually the entire commodity DRAM business to our DRAM patents.

Over the years, we’ve strengthened our DRAM-related portfolio with the acquisition of patents from semiconductor leaders such as Samsung, Hynix and Micron Technologies. We now own one of the world’s best memory portfolios—hundreds of patents and applications related to DRAM and other memory technologies. The importance of this portfolio is reflected in our continued licensing success, repeatedly signing new licenses and license renewals for over 20 years.

Flash Memory Patents
Flash memory is a type of electronic memory commonly used in portable electronic devices and data storage medium such as SSD (Solid-State-Drives). With the growing popularity of mobile computing and data centers for cloud computing, artificial intelligence or big data analytics, Flash memory is becoming the biggest semiconductor sector in a growth market.

Embedded Memory Patents
Whereas a DRAM or Flash memory chip is typically a “standalone” or discrete device, “embedded memory” is a type of memory that is integrated, or built, into a multi-function semiconductor device. Embedded memory is often used in high-performance microprocessors and consumer products such as game consoles.

MOSAID has filed, and also acquired, far-reaching patents related to both embedded memory and Static RAM (SRAM) technologies. We believe our technology is used widely in embedded memory solutions such as Application Specific Integrated Circuits (ASICs), System-on-Chip (SoC) products, and microprocessor technologies. Our Embedded Memory patent portfolio continues to grow through synergies with our world-leading memory portfolio, and acquisitions.
