I have a hardware that supports a limited size of non-volatile RAM. So, I'd like to utilize it in Sqlite database. I found that the journal_mode can be set to MEMORY which means the journal file will be stored to the memory. Can I specify this memory address and size ? For example, the NVRAM address is mapped to the memory address 0x10000 and its size is 512KB. So, can I set the journal file to store at the address 0x10000 and the jouranl size limit be set to 512*1024 bytes ?
