Abstract: An example apparatus includes: bandwidth estimator circuitry configured to: obtain a first memory transaction; and determine a consumed bandwidth associated with the memory transaction; and gate circuitry configured to: permit transmission of the memory transaction to a memory controller circuitry; determine whether to gate a second memory transaction generated by a source of the first memory transaction based on the consumed bandwidth of the first memory transaction; and when it is determined to gate the second memory transaction, prevent transmission of the second memory transaction for an amount of time based on the consumed bandwidth.

Abstract: Methods, apparatus, systems, and articles of manufacture are described to facilitate access control in memory. An example method includes accessing state values stored in non-volatile memory, the state values corresponding to a state of the non-volatile memory; responsive to obtaining a request to enter a diagnostic mode, authenticating credentials corresponding to the request; determining the state of the non-volatile memory based on the state values; and determining whether to permit or prohibit access to the non-volatile memory based on the determined state.
