This document provides a user guide for the internal memory (RAM and ROM) of Altera Corporation, including the features and characteristics of the products.
This document serves as a user guide for Altera's Internal Memory blocks, specifically covering RAM (1-Port and 2-Port) and ROM (1-Port and 2-Port) modes. It details the two megafunctions provided for these implementations: ALTSYNCRAM and ALTDPRAM. The Quartus II software automatically selects the appropriate megafunction based on the target device and memory mode features.
The guide assumes familiarity with Altera megafunctions and the MegaWizard Plug-In Manager. It outlines various configurable features including memory modes, block types, write and read operations, port width configuration, clocking modes, byte enable, asynchronous clear, and error correction code capabilities.
