The internal flash memory structure

[Satheeshkumar]

Hi,

I have a simple and basic question. it may be chilly. the internal flash memory can store the data, but the question is it has stored as byte per address or word per address.

is the memory architecture is 32G X 8bits or 32G X 32bits? how to determine the 256kb memory size? and what storage structure?

example:-

the address is 0x00027000 and data is 0x41424344. how has it stored?

                      0x00027000=0x41424344 this right? or

like this format,

                      0x00027000=0x41

                      0x00027001=0x42

                      0x00027002=0x43

                      0x00027003=0x44

or another format

                      0x00027000=0x00000041

                      0x00027001=0x00000042

                      0x00027002=0x00000043

                      0x00027003=0x00000044

thanks in advance.

ARM Cortex-M has byte addresses, but it can load 4 bytes at once if the two least signifcant bits in the address are zero. Note that the 256KB are KB and not kb (Kilo Byte instead of kilo bits), so it will be 256*1024 bytes of data capacity.

yeah I got the answer myself I was confused little bit about memory organization now I cleared thanks for the reply
