Mentor Graphics coolSRAM-1T embedded memory IP is the industry’s only silicon-proven, single transistor SRAM IP solution that can be implemented in a bulk logic CMOS process without requiring additional masks or manufacturing steps. Use of coolSRAM-1T lowers overall system level cost by reducing both the area of standard embedded SRAM and the number of external components. coolSRAM-1T is used in circuits that require minimized block size with conservative speed. This can be complemented with coolSRAM-6T, coolSRAM-8T, coolREG-6T, and coolREG-8T for high speed applications.

Based on Mentor patented SRAM-1T technology, coolSRAM-1T is an ideal solution for high-density SRAM integration in ASICs, ASSPs, VLSI and System-on-Chip (SoC) applications. Embedded coolSRAM-1T blocks are custom configured by the designer and compiled to meet the design specifications, providing an unprecedented mix of low power and high density to minimize total system cost.

Like all Mentor Graphics embedded memory IP, coolSRAM-1T can be customized via the MemQuest memory compiler, a Web-based on-line tool suite that enables the SoC designer to specify and implement custom memories in a matter of minutes.
