New Technology Goes Beyond OTP

June 9, 2011

Silicon-IP (intellectual-property) vendor Kilopass Technology has added multitime programmability to antifuse-based nonvolatile memory. An antifuse-based memory can be programmed by breaking down a silicon-oxide barrier to set the state of the memory bit in a two-transistor cell. Like a ROM, programming with antifuse memory has traditionally been an OTP (one-time-programmable) process. With the announcement of Itera technology, Kilopass adds multitime programmability of as many as 1024 cycles for memories with as much as 1 Mbit of storage capacity.
