ROM (Read Only Memory) is for the permanent storage of data within an SoC or other integrated circuit application. ARM offers both Via Programmable ROM and Diffussion Programmable ROM delivering maximum flexibility in design application.
  • High density and low power ROM memories suitable for BOOT code
  • Broad support for all leading EDA vendors ensuring quick time to market Flexible business models like ‘free library program’ and ‘try before you buy’ allowing lowest cost of ownership
  • Memory subcircuits optimized over multiple sub ranges to provide power, performance and area close to a custom design.
  • Lowest risk solutions with ARM memories being used by IDMs, fabless start-ups, IC companies and design houses backed up by a knowledgeable customer support team available in multiple time zones

High Density memories are 30% smaller compared to High speed memories and designed for high array efficiency. Targeted for mainstream and cost sensitive applications, these memories and can achieve up to 7000Kbits/sq mm at 28nm technology.                      

 

Targeted for power sensitive handheld markets, these Low Power memories reduce leakage current by up to 30% over the standard memories. These memories are . Multiple power management modes available providing up to 20x reduction in leakage in power down mode over the regular standby mode                         


  • Depending upon foundry, geometry and flavor the Register file compilers support multiple features to ensure optimal implementation of all types of designs
