Simtek Confidential
Ramtron 1 Mb Summary
Be Careful of the Ramtron Marketing Propaganda
Ramtron claims a 60 ns part for their 1Mb FRAM, and marks it
appropriately on the package
This is only part of the truth!
Their read/write cycle time for commercial temp is 150 ns, 6 times
slower than Simtek’s 1 Mb
Their read/write cycle time for industrial temp is 350 ns, 14 times
slower than Simtek’s 1 Mb
The 60 ns access is for Chip Enable access, a non-standard way of
operation during regular microprocessor accesses. But it doesn’t
include a 90 ns pre-charge time.
