write to segment (multiple locations) of memory

Hi,

memory blocks are -as you certainly know - are ASIC like memory structures within fpgas accessible to logic through their ports and configurable through megawizard or code... into rams or roms or fifos or shift function.

I don't know what you mean exactly by memory block as opposed to these blocks. a ram has access through its ports, so is the rom and so is fifo or shift function.

You will need to click on megawizard (tool menu) and choose memory compiler then choose your configuration.
