Hi,

I suppose that there is not erasing concept for SRAM,you can write any data at any time to an address of SRAM. In general, after reset, the data in SRAM is random, even if the data in SRAM are all zero, you can not take it for granted.

Hope it can help you

To expand on that, SRAM is usually initialized in the startup code.
Most regions are cleared (to zero), others are initialized with constant data from Flash, according to the linker script settings.

If one want to change this behavior, this would be the place to implement it, i.e. the startup code in connection with the linker script and section definitions.
