Innodisk's new iRetention™ is strengthening data retention
through firmware and hardware optimization
TAIPEI, Taiwan, May 17, 2018 /PRNewswire/ -- Flash memory is a
non-volatile storage medium. This means that data remains on the
Solid State Drive (SSD) without power. There are, however,
certain factors that can lead to data loss and data
degradation.
Data Retention: Temperature and P/E Cycles
High temperature and frequent program/erase (P/E) cycles can
both severely impact data retention. Every cell inside flash traps
a negative charge that represents a binary value (e.g. 01, 10
etc.). These cells are generally
good at holding on to this charge, but every now and then
some of the charge will leak out. An
error correction code is normally
good at picking this up and fixing the problem.
High temperatures will, however, speed up the rate of leakage.
Testing shows that the data retention of standard MLC flash
decreases 168-fold when moving from 40°C to 85°C. This means data
that would normally last 2 years, will experience issues in 5 days. The problem is further exacerbated as the
number of P/E cycles increases, meaning that SSDs in heavy-writing
environments are particularly at risk.
iRetention™
Innodisk's new iRetention™ technology tackles this problem
through smart firmware and hardware innovations. An onboard sensor
will constantly monitor temperatures, which, along with the P/E cycle number, are used
to calculate how often to refresh the data. This is all handled by
the SSD itself and will self-adjust to changes in the
environment.
iRetention™ is perfect for devices that see extreme temperatures
and thermal variation. This makes it suitable for application such
as in-vehicle, automation, food processing, aerospace and defense. Innodisk
will showcase iRetention™ at this year's Computex in Taipei:
