CustomIP™ is set of silicon-proven, specialty memory architectures optimized for a variety of IC applications. Spectral has the broadest range of memory compiler architectures including experience with specialty designs such as Binary and Ternary CAMs, Multi-Ported memories, Low Voltage SRAMs, Cache, eFlash. These are just some of the architectures in the Spectral family. Spectral’s solutions use foundry or Spectral custom designed bit cells that enable robust operation. They integrate high density, low power architectural design as well as performance optimized circuitry to attain high speed operation with minimal power consumption. Coupled with Spectral’s Memory Development Platform, CustomIP™ is also available in source code format so that users can modify the designs, port to other technologies or extend the capabilities. Spectral CustomIP™ is designed for standard CMOS process technology, SOI or embedded Flash processes.

      All Spectral CustomIP™ utilizes SpectralTrak™ technology which is proprietary PVT monitoring circuitry that accurately and dynamically detects changes in Process, Voltage and Temperature environmental conditions to insure that critical internal memory timing pathways are within allowable margin tolerances.

      Product Description

      All Spectral CustomIP™ is architected for high density and low dynamic power consumption. Providing a broad range of memory compiler designs offers chip designers memory IP that is optimized for the variety of embedded storage requirements needed to realize complex memory subsystems. SpectralTCAM is used for networking or fast hardware search requirements. SpectralMPort is popular with certain graphics applications. Spectral low voltage and proprietary caching SRAMs are well suited for consumer mobile and hearing aids, while SpectralHRAM (Hibernate RAM) consumes nano-amps of standby current while retaining data for metering and medical devices.

      CustomIP™ can be used by companies to provide a rich set of specialty memories not commonly available by other vendors to product groups trying to differentiate their ICs. It can also be used by companies that desire to internally develop and maintain control of the memory IP. For companies desiring to take control of memory IP development, CustomIP™ provides a comprehensive set of silicon proven architectures developed in the world’s most productive memory compiler development platform, MemoryCanvas™ and MemoryTime™. Spectral offers optional rights to modify. These custom compilers all offer many features such as power down, test modes, multiple aspect ratios, multi-bank and are fully compatible with advanced process nodes.
      CustomIP™ from Spectral is compatible with, and can be used in place of, memories provided by commercial foundries or other IP vendor companies.
