Hallo,

I'm a bit confused when memory wide ans memory size comes in question. When reading about different memory blocks I frequently come across on something like this: Program memory 512b wide 88Kbytes size.

What that exactly means? What is the difference in comparison with let's say: Program memory 32b wide 32Kbytes size.

Thanks
 

Memory WIDTH is the size of each element in your memory. Size is, well, size of the memory. If you take the WIDTH and multiply it by the DEPTH, you'll get the size. For your second example, you've got a size of 32Kbytes=>256K bits. Since your data are 32bits wide, this memory will be 8K deep (8192 locations)
 

OK. So 8192 memory locations, each of which stores data that is 32bits wide (if integer a number from 0 to 2^32). Memory WIDTH = Data WIDTH?
Thanks!
