Temperature dependence of Read and write endurance (FRAM)

Hi,

read or write endurance of FRAM,
Is there data of the temperature dependency?

I'm waiting for an answer.

Best Regards,

The datasheet specifies the endurance as 10¹⁵ cycles minimum, over recommended ranges of supply voltage and operating free-air temperature (-40°C to 85°C).

Are you planning to run outside that temperature range, or do you want data on how much higher the endurance might be at a specific temperature in the range?

Hi, Robert

Thank you for reply.

It's used in the recommendation temperature range of the chip.

I'm thinking with Free-Air- it isn't 85 ℃ of to 40 ℃.
Could you tell me a view to TI emploee?

Hamada,

could you please specify your question in more detail? As Robert said, TI gives a read/write endurance for a specified temperature range. Do you now want to know if the endurance increases when not using the complete temperature range? Or do you just want a TI employee to confirm the specification given in the datasheet?

Hamada has confirmed that "It's used in the recommendation temperature range of the chip."

I think the key issue - as mentioned in the last reply - is this:

Unfortunately I can't quite understand what hamada is saying here. Perhaps if this is explained in more detail we (or someone from TI) can provide an answer.
