hi, i am quite new to vhdl and quartus ii. i have coded a 16x8 ram using vhdl in quartus , and y need a ram of 256kb , when y chage the address_width to 131072, that is the number of bits that...

Honored ContributorAlso, are you sure you're smaller test case really uses the embedded memory? The out of memory error is not anything to do with memory in the FPGA, but that the physical RAM the synthesis process required was more than 2GB and the operating system probably capped it at 2GB. Under normal RAM inference, synthesis knows it's a single unit and it hardly uses any memory at all, but if the RAM gets synthesized into gates(registers, muxes, etc.) than it's an enormous structure(and surely not what you want).
