摘要
An improved method for performing a write through operation during a write operation of a SRAM cell (10) of a SRAM array (1) is disclosed. The method comprises suppressing a false write through data propagation at an output node (C, F) of the SRAM array (1) in case of a failure causing transition at a first node (t) or a second node (c) of the SRAM cell (10) by using information about the input data (data, data_b) to be written in the SRAM cell (10) and read data propagation paths to retain the output node (C, F) after a global bit line (gb_t, gb_c) at a precharge level independently from a logical level of the global bit line (gb_t, gb_c), if a corresponding node (c, t) of the SRAM cell (10) is performing the failure causing transition based on input data (data, data_b) to be written in the SRAM cell (10).
