A memory circuit includes a plurality of banks and a controller, each bank of the plurality of banks includes a plurality of segments, and each segment of the plurality of segments includes a plurality of bit lines and a plurality of word lines. A word line switch corresponding to a word line of a segment of the memory circuit is turned on and data are written into memory cells of the segment coupled to a plurality of bit lines of the segment and corresponding to the word line in turn after the controller enables an active command corresponding to the word line. When the controller enables at least one copy row write command, the data are simultaneously written into memory cells sharing a plurality of sense amplifiers with the plurality of bit lines of the segment and corresponding to at least one another word line.

Memory circuit with improved read and write access

A memory circuit capable of being quickly written in data includes a plurality of banks, and each bank of the plurality of banks includes a plurality of segments. Each segment of the plurality of segments includes a plurality of bit line groups, and each bit line group of the plurality of bit line groups corresponds to a pre-charge line. When a predetermined signal is enabled, a potential is written into memory cells of the each segment corresponding to the each bit line group through the pre-charge line and the each bit line group.

Memory circuit capable of being quickly written in data

A method of operating a PSRAM includes selecting a bit on a word line of the PSRAM, keeping the word line on for a first predetermined duration after selecting the bit, writing a data into the bit in response to a write command, and keeping the word line on for a second predetermined duration after the write command ends.

Method of providing write recovery protection in PSRAM and related device

A method for increasing responding speed and lifespan of a buffer includes detecting an edge of an input signal of the buffer, triggering a pulse signal with a predetermined period according to the detected edge, and driving the buffer for generating an output signal according to the pulse signal and the input signal.
