Problems solved by technology

Because multiple storage units are involved, sometimes the input signal of the signal transmission circuit is to input multiple signals in parallel at the same time, but the output needs to be output one by one. For example, the output of the memory system read signal reads multiple storage units at the same time. signal, but the output requires the storage information of a single storage unit to be output one by one, so it is necessary to design an input and output circuit with a simple structure and fast data transmission

Abstract

The invention provides a parallel input serial output circuit and a memory using the same. The parallel input serial output circuit comprises a timer circuit, a decoder circuit, a multiplexer circuitand a D trigger. The timer circuit generates counting signals according to different clock periods, the decoder generates different selection signals according to the counting signals, the multiplexerreceives parallel input signals and outputs serial input signals under the control of the selection signals, and the serial input signals pass through the D trigger to output serial output signals. The parallel input serial output circuit is simple in structure and can realize high-speed conversion and transmission of data.

Description

technical field [0001] The invention relates to the field of circuit design, in particular to the field of data input and output circuits and a memory using the data input and output circuits. Background technique [0002] A memory system usually includes a plurality of memory cell arrays, and various signal transmission circuits are required to implement signal transmission when performing read and write operation control on the multiple memory cell arrays. Because multiple storage units are involved, sometimes the input signal of the signal transmission circuit is to input multiple signals in parallel at the same time, but the output needs to be output one by one. For example, the output of the memory system read signal reads multiple storage units at the same time. The signal, but the output requires the storage information of a single storage unit to be output one by one, so it is necessary to design an input and output circuit with a simple structure and fast data trans...
