A look at the alternatives to ROM and their benefits, including lower cost, better performance, secure storage and configurability.
With complexity of SOCs growing and time to market cycles shortening, designers need to have an arsenal of tricks to deliver highly differentiated products to market quickly. The arsenal may include SystemC, EDA tools to achieve a faster timing closure, and IP from high speed I/Os to memories. The most pervasive memory IPs are SRAM and ROM. Less pervasive memory IPs include non-volatile memory (NVM) technologies such as embedded Flash, electrical fuses, multi-time programmable (MTP) NVM, and one-time programmable (OTP) eNVM. Though these embedded NVM technologies are not as mainstream as their ROM sibling, they are gaining in popularity due to various added benefits including cost reduction, improved performance, enabling secure storage, and configurability. In this paper you will learn about all the embedded NVM technologies and the applications that benefit most from using embedded NVM.
