Apparatus for burning pagination of scrubbed and programmable ROM as well as control method thereof

Abstract

The invention discloses a paging recorder of a washable programmable read-only memory and a control method thereof, wherein the recorder comprises an input / output buffer, which is coupled with the washable programmable read-only memory. The recorder further comprises a plurality of writing circuits and a readout circuit, wherein the writing circuits are used to parallelly write input data in the washable programmable read-only memory, and the readout circuit is used to read out output data from the washable programmable read-only memory. Using the invention, the defect that writing stroke by stroke wastes time when a traditional washable programmable read-only memory is burned can be improved, the paging recorder parallelly sends many strokes data in one time and burns simultaneously, thereby being capable of greatly reducing the burning time, increasing the production time course, and being capable of reducing the cost of detecting if the paging recorder is applied in a test.

Description

technical field [0001] The present invention relates to a page write mechanism of an erasable programmable read-only memory (EPROM), especially a device with a plurality of write circuits and a readout A page-programming device for an erasable programmable read-only memory of a read circuit, for writing an input data in parallel to the erasable programmable read-only memory and reading an output from the erasable programmable read-only memory material. Background technique [0002] Erasable programmable read-only memory is a kind of non-volatile memory. The stored data (data) still exists after the power disappears, and the internal data of the memory can be cleared by irradiating ultraviolet light, and then used to burn The device rewrites the data to achieve the purpose of repeated erasing. When traditional erasable programmable read-only memory is written, it is written in data format one byte (byte) / 8 bits (bit) or one byte (word) / 16 bits at a time. However, each write...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a paging programming device for erasable programmable read-only memory and its control method, which can improve the time-consuming shortcomings of writing one by one when traditional erasable programmable read-only memory is programmed , the page-by-page programming device can greatly shorten the programming time and speed up the production schedule by sending multiple pieces of data in parallel at one time and burning them at the same time. If it is used in testing, it can reduce the testing cost
