Hullo guys , ....... from the memory map on STM32F2XX datasheet , each GPIO takes 1024 bytes space from memory , I wonder why? ........ each GPIO has 10 32-bit registers , does not that means 40 bytes per GPIO ? ......... thx in advance

I wonder why?

Decoder circuit complexity is reduced. Simpler schemes use less silicon. It's not ''memory'', and the behaviour of a specific address may differ between read/write contexts.
