SnapXPM

SnapXPM Pre-Configured Embedded Non-Volatile Memory

SnapXPM is a library of pre-configured non-volatile memories across more than 10 semiconductor process technologies, offered at a 20% to 30% discount. The library includes 25 XPM modules that are most commonly used in customers’ designs, and are sold off-the-shelf to offer a faster time-to-market, and lower cost solution .  In addition, it supports various configuration options to avoid extra waste and thus saves silicon area. Snap XPM is available from 180nm to 65nm at foundries including TSMC, SMIC, Tower, and Dongbu. Its configuration options include density, read voltage, program/read bus width, and charge pump.
