How primary memory is organised in a microcontroller? : <p>My query is :How the memory is organized and managed in the microcontroller?
(It doesn't have any OS i.e no presence of MMU).</p>

<p>I am working over zynq 7000 (ZC702) FPGA,It has seperate arm core and seperate DDR memory connected together with axi interconnects.</p>

<p>I wrote 11 1111 1111 in decimal to DDR(10 1's),it is giving me same after reading.
when i write 111 1111 1111 in decimal to DDR(11 1's),it gives me -1.</p>

<p>here the whole physical memory is consumed.This will not be the case when i use any microcontroller.
Who will manage the memory in microcontroller?</p>
