Datum programming circuit for one-time programmable memory and method thereof

Abstract

The invention relates to a datum programming circuit for a one-time programmable memory and a method thereof. The datum programming circuit comprises a one-time programmable memory and a control unit. The control unit stores multiple segments of a reading only memory code to an unused space in the one-time programmable memory, and corresponds with same content segments in the multiple segments. The control unit stores a specific address to the one-time programmable memory.

Description

technical field [0001] The invention relates to a one-time-programmable (OTP) memory, in particular to a data programming method of the one-time-programmable memory. Background technique [0002] With the rapid development of personal electronic products, solid-state data storage technology has become increasingly important. In portable consumer electronic products, solid-state data storage devices are moving towards the goal of miniaturization, simplicity and low cost. Solid-state data storage technologies (such as Erasable Programmable Read-Only Memory (EPROM), Electronically Erasable Programmable Read-Only Memory (EEPROM), etc.) are very suitable for developing high-speed application devices, especially high-speed applications with complex and expensive programs device. [0003] However, for many consumer electronics products, low cost will be more important than high speed. Therefore, a non-volatile one-time programmable memory with low manufacturing cost and stored d...

Problems solved by technology

In addition, one-time programmable memory can only program data once

In other words, once the memory cell in the one-time programmable memory is programmed, the data stored in the memory cell cannot be corrected.
