Embedded Memory Compilers
High density / Low power embedded memory compilers
For more than 25 years, Dolphin Integration has continuously enriched its embedded memory IP portfolio to provide high-quality ROM, SRAM, and Register File Memory-compilers, available from 180nm down to 28nm in various foundries and process variants.
Dolphin Integration’s memory-compilers are optimized for high-density and low-power while providing a great flexibility and a fine granularity providing the designers with the capacity to find the optimal trade-off between performance, power and area.
Our embedded memories are endowed with multiple power saving features (various power saving modes, embedded power switches with in-rush current limiter, source-biasing, multi-VT periphery…) to minimize both static and dynamic power consumption. Moreover, options for overdrive/low-voltage PVTs and for dual-power rail makes possible to support dynamic voltage and frequency scaling (DVFS).
Dolphin Integration’s memory-compilers are extensively silicon proven, and designed to provide highest yield thanks to our thorough validation methods.

SRAM and Register Files
Dolphin Integration’s SRAM and register file compilers have been designed to achieve minimum area and power while meeting aggressive timing requirements.
Single port (SP), dual port (DP) or 2-port memory (2P) compilers are available, depending on the technology node.
These best-in-class memory compilers rely on a smart architecture to provide the optimal solution to various design needs in terms of performance, power and area combinations.
Multiple Power Management Modes
Multiple low power modes are available, enabling power-optimized SoC design with the flexibility to select the best compromise between power saving and response time. Retention and shut-down modes provide a progressive reduction of leakage power compared to stand-by mode.
Several options to address various needs
To reach low power and exploit all the benefit the technology can offer, Dolphin Integration, propose a large choice of options for SRAM that can be combined at ease. (Move on GIF to access on details)
ROM memory compilers
From the inception of the company, Dolphin Integration has acquired a strong know-how in Via ROM design that has resulted in multi-patented ROM compilers. Thanks to its unique bit-cell and its power aware architecture, Dolphin Integration’s Via ROM represents the best combination of high density and low power available on the market.
A compact via programmable ROM array (with a single programming layer) featuring high-speed read enabled by reduced stray capacitance. sROMet enables reduced area with lower dynamic consumption compared to traditional via ROM.
Its multi-bit data per ROM cell, featuring ultra-high-density, targets high capacity ROM up to 8 Mb. This patented architecture offers huge area reduction while keeping a reduced dynamic consumption compared to traditional ROM.

Memory Test and Repair features
Test & diagnosis of embedded memories need to be performed at speed in deep submicron process nodes. Extensive use of memory-BIST (Built-In-Self-Test) thus becomes mandatory.
Test and debug
- Proprietary Memory BIST
- Debug and diagnostic option enables SoC integrators to identify errors and to specify whether these errors are due to the process or due to the design. This option helps to diagnose yield loss and to define the appropriate corrective actions.
- Fill/check option enables to fill the whole memory with a given pattern and to check that each write & read operation is successful.
- Full support of Tessent Memory BIST (from Mentor)
- Key for supporting SoCs with a large number of memory instances
- Fully automated & integrated BIST insertion
Repair and redundancy
- Self Repairable RAM (starting from 28nm) supporting various redundancy schemes.
- Easy control of Area, Speed and Yield trade-off
