What is the difference between logical right shift and arithmetic right shift of LSR in RAM?

What is the difference between logical right shift and arithmetic right shift of LSR in RAM?

For example, for an 8-bit binary number 11001101 with signed bit, logical right shift does not care about the sign bit, if one bit is moved, it will become 01100110. Arithmetic right shift needs to manage the sign bit, and right shift one bit will become 10100110. Logical left shift = arithmetic left shift, add 0 to the right, logical right shift, add 0 to the left, arithmetic right shift, numbers and symbols added to the left
