A spin transfer torque magnetic random access memory (STT-MRAM) device according to the present embodiment comprises: an STT-MRAM memory array which includes a data storage unit for storing data, a defect area address storage unit for storing an address of a defect area, and a spare area for storing data of a failed area; and a bypass determination unit which includes a volatile information storage element for storing the address of the defect area, stored in the defect area address storage unit and provided thereto, and when memory array access occurs, compares an access address with the address of the defect area stored in the volatile information storage element and causes the memory array access to bypass to the spare area.

STT-MRAM failed address bypass circuit and STT-MRAM device including same

A semiconductor memory system comprising: a memory device including a plurality of data cells; a read/write circuit suitable for performing a write operation to a target data cell among the data cells; and a state transition recognition circuit suitable for detecting a state transition of the target data cell, and ending the write operation according to the detection result of the state transition of the target data cell.

Semiconductor memory system and operating method thereof

An image forming apparatus including at least one option cassette, and a paper jam handling method performed in the image forming apparatus are provided. The paper jam handling method includes the operations of detecting whether paper jam occurs in the image forming apparatus, checking whether paper sheets exist on a transfer path of the image forming apparatus and on a transfer path of the option cassette, when the paper jam is detected, and leaving the paper sheet on the transfer path of the option cassette as it is and discharging the paper sheet caught on the transfer path of the image forming apparatus. Accordingly, paper damage or paper consumption may be prevented by not discharging a paper sheet caught on a transfer path of at least one option cassette during paper jam.

Method for processing paper jam in image forming apparatus having at least one option cassette, and image forming apparatus that performs the method

An image printing method of a host apparatus connected to an image forming apparatus, the method includes selecting an image to be successively printed over a plurality of recording pages, disposing the image to be successively printed on at least one of top, bottom, right and left positions of at least one of the plurality of recording pages, generating printing data of the image to be successively printed over the plurality of recording pages, and transmitting the printing data to the image forming apparatus.
