OTP HD is a high-density, one-time programmable memory solution built upon eMemory’s proprietary NeoBit technology.

Availability

NeoBit HD is available for different generations of logic technology (0.5/0.35/0.25/0.18/0.16/0.13/0.11um) and can be easily ported to logic-derivative technologies, such as mixed-mode, RF, analog, high-voltage, and embedded memory, without changing any process or its device simulation model. Densities for NeoBit HD range from 512K to multi-K bits, and I/O configuration possibilities include x8~ x16-bits.

Advantages

The advantages of NeoBit HD over traditional embedded and external memory products include:

Technical Principles

NeoBit HD aims to provide high-density memory IP with testability for code storage and parameter setting application. NeoBit HD comprises of a memory array and function blocks allowing programming and read designate for memory cells.

Block Diagram: NeoBit OTP HD (Standard)

Programming voltage of 6.5V~7.5V supplied by external power is needed only during the programming period and some standard blocks include a power switch for more flexibility. Charge pumping is not available on standard NeoBit HD in order to reduce the size of the memory. Customized IP is available for users requiring charge pumping.
