Publication number: 20230280933Abstract: A slave provides second data bits and ECC bits in response to a master read request. First data bits are generated by selecting between the second data bits and third data bits produced from error correcting the second data bits. The third data bits are generated with a delay of one clock cycle with respect to the second data bits. If an address of the read request is stored to a memory, a control signal is set indicating that the first data bits are invalid and this drives selection of the third data bits (with the first data bits now being valid in a following clock cycle). If an error signal is asserted when the address is not stored to the memory, action is taken to store the address to the memory and a further control signal is set to indicate that the read request should be repeated.Type: ApplicationFiled: March 2, 2023Publication date: September 7, 2023Applicant: STMicroelectronics S.r.l.Inventor: Federico GOLLER

Publication number: 20230283252Abstract: An internal voltage offset between a positive input and a negative input of a first operational amplifier is compensated. The negative input and the positive input of the first operational amplifier are coupled at the same voltage level.
