Is there an accessible Sleep memory (RAM) in BC660K_GL?

Hi, i wanted to ask if there is a sleeping memory (RAM) in BC660K_GL. By sleep memory I mean, where data is not lost in deep sleep.

In BC66, there was a page of 256B which was working for me well.

According to the memory organization (during clean/make),
I see the following outputs,

UNLOAD_DRAM_SLPMEM: 224 B 992 B 22.58%

Is this the part of memory that is not lost during deep sleep, also is it accessible to users in quecopen environment (i mean is it safe)?

If this is not the case, then is there a part of non volatile memory (RAM), that can sever this pupose (not the file system)?

If this memory is what I need, then how come its already 22.58% filled, I have not written anything myself here, which means the module is already using this part of memory for some purpose.
`
Best Regards.

please use file system,and refer example_fs.c

yes, i know the file system is there, but my data is very small and will be written in high frequency.
Don’t want to use the filesystem for this.
Is there no such ram or part of ram that exists for BC660K_GL?

Sorry, we cannot provide the use of RAM, the chip itself does not have the release permission to Quectel

ok, thats what I wanted to confirm.
Thanks
