Nor Flash
The NOR Flash Memory forum discusses critical safety features for automotive and industrial systems, and Semper NOR Flash Memory with ASIL-B compliant and ASIL-D-ready.
Hyper Flash
The HyperFlash NOR Flash memories Forum offers discussions on automotive advanced driver assistance systems (ADAS), automotive instrument cluster, automotive infotainment systems, and communication equipment.
Hyper RAM
HyperRAM™ memory Forum discusses self-refresh DRAM operating on the 12-pin HyperBus interface. With a read throughput up to 333 MB/s, the HyperRAM for SoCs with limited on-board RAM providing external scratch-pad memory for fast read and write operations.
Non Volatile RAM (F-RAM & NVSRAM)
Non-volatile RAM forum discusses Technology such as F-RAM and nvSRAM, which combine non-volatile data storage up to 16Mbit density with the high performance of RAM. These low-power memories offer high endurance, high data retention and instant non-volatility without external battery back-up, enabling system reliability and cost reduction.

Assuming capacitive load only, IO power can be estimated to be ((α)* f *N * CL* V * V)
where
α is called the activity factor ; if on an average half the IO's switch per clock cycle, then α is 0.5.
f is the switching frequency or clock frequency
N is the number of IO's
CL is the capacitive load;
V is the Voltage swing of the IO.
For example: IO power for (CYD18S36V18) = (10MHz * 36 * 20pF * 3.3^2)/2 = 39.2mW.

Guys,
I recently figured out a nice thing about NVSRAM operation and thought it is worth sharing with everyone.
If NVSRAM is attempting AutoRecall and the power fails, AutoRecall will stop and next time the power comes back, previously stored (during AutoStore operation of course) data will be recalled. Similarly if power comes back during AutoStore operation, AutoStore operation will still be carried out and then AutoRecall will take place. In the end, it is not going to pose any problem in such corner cases....
cheers !
Thanks in Advance for any help.
