Semiconductor system and operating method thereof

A semiconductor system, comprising:

• a selector circuit configured to generate a select signal according to an input data having a first accumulation size;
• a buffer circuit having a second accumulation size, and configured to store the input data when the select signal has a first logic value;
• and
• a memory array configured to store the input data when the select signal has a second logic value and transmit the input data to the buffer circuit;
• wherein when the first accumulation size is smaller than the second accumulation size, the select signal has the first logic value, and
• when the first accumulation size is larger than the second accumulation size, the select signal has the second logic value.

A method, comprising:

• receiving an input data having a first accumulation size;
• comparing the first accumulation size with a second accumulation size of a buffer circuit;
• storing the input data from a write circuit to a memory array when the first accumulation size is larger than the second accumulation size;
• storing the input data from the write circuit to the buffer circuit when the first accumulation size is smaller than the second accumulation size;
• transmitting the input data from the memory array to the buffer circuit when the first accumulation size is larger than the second accumulation size;
• and
• transmitting the input data from the buffer circuit to a computing circuit.
