ISSI intros high speed SRAM with error correction

SAN JOSE, USA: Integrated Silicon Solution Inc., a leader in advanced memory solutions, has introduced the ECC based IS64WV25616EDBLL, a 4Mb high speed asynchronous SRAM.

This device is designed to provide a high speed asynchronous SRAM solution with enhanced data integrity that is form-fit-function compatible with current industry standard devices without ECC.

The IS64WV25616EDBLL is organized as 256Kx16 and has an operating voltage range of 2.4V to 3.6V. The device is offered in 44-pin TSOPII and 48-Pin BGA packages. To provide enhanced reliability, the 44-pin TSOPII is a copper lead frame based product. IS64WV25616EDBLL is offered in both leaded and lead free options to address various customer requirements.

This unique solution from ISSI is based on 65nm technology and draws only 45mA operating current when operated in the range of -40 to 85C. Typical operating current is only 25mA. The device is offered in an industry leading 10ns access time, and can support -40 to 85C and -40 to 125C temperature ranges.

The error detection scheme is based on an independent hamming code for each byte. The device detects and corrects one bit errors for each byte. The device provides better reliability than parity code schemes which can only detect an error, but not correct it.

"ISSI's IS64WV25616EDBLL provides a high quality and high reliability solution that a number of automotive customers have been looking for," said Lyn Zastrow, ISSI vice president of the Automotive Business Unit. "The Error Correction is very attractive for many automotive applications especially engine and transmission control."

A 512Kx8 option offered in a 44-pin TSOPII will be available in April, 2011. A 1.8V option will be available in June, 2011.

"The IS64WV25616EDBLL is well suited for Mil-Aero and other ruggedized applications requiring error – free memory," said Sean Long, ISSI director of marketing, Industrial, Medical, Mil-Aero Business Unit (IMM). "In addition to the broad feature set, ISSI's commitment to provide long term support is a great added value that many IMM customers require."

The IS64WV25616EDBLL, combined with extended temperature and a variety of options, make this product ideal for automotive, industrial, medical, Mil-Aero and telecom/networking applications.
