OTP ULP is a ultra low-power, one-time programmable memory solution ideally suited to the low-power, low-voltage memory requirements of RFIC chips.

Availability

NeoBit ULP is available for three CMOS-compatible process generations including 0.35um, 0.25um, 0.18um, and compatible with all logic-based processes. Memory densities are available from 256 to 2K bits.

Advantages

In eMemory's IP family, NeoBit ULP is a series that is especially well suited for RFID system. NeoBit ULP is a highly flexible and cost-effective alternative to conventional OTP solutions. Large margins and time savings during production, along with optimal performance and its impressive yield, can be achieved by implementing eMemory's logic-based IP in tag ICs--all without the need for extra masks.

Technical Principles

NeoBit ULP operates at low voltage and features a low programming and access current. Unlike the byte programming found in NeoBit HD and HR, NeoBit ULP programs memory cells bit by bit to save power. In addition, the complete HV system and power switch are included in standard NeoBit ULP IP as shown in the following.
