Abstract

The invention discloses a data relay structure for a configuration memory of a programmable logic device, and relates to the technical field of programmable logic devices. The data relay structure includes cascading of several distributed data relay modules, and each data The relay module is composed of the pre-charged read-write module, the read-back module and the pre-charged shielding module with an enable terminal as the core. It does not occupy additional register units and is flexible. It can realize memory clearing, configuration data writing and configuration data return. Read three functions, and remove the pre-charge stage during the configuration data writing process, without charging RBL and RBLN to high level, thus reducing RBL voltage loss and programming power consumption, very suitable for ultra-large-scale programmable devices Configuration.

Description

technical field [0001] The invention relates to the technical field of programmable logic devices, in particular to a data relay structure for a configuration memory of a programmable logic device. Background technique [0002] Programmable logic device, based on the storage technology of repeated configuration, completes the modification of the circuit by re-downloading programming, has the advantages of short development cycle, low cost, low risk, and easy maintenance and upgrade of electronic systems, so it has become the mainstream of integrated circuit chips . Configuration memory is one of the most common functions in logic applications of programmable logic devices. Through configuration memory, the functions of data clearing / data configuration / data readback of the chip can be realized. [0003] Many complex integrated circuit chips need to load configuration information after the chip is reset, or reload specified configuration information in the working state. fig...
