Abstract
Methods, apparatus, systems, and articles of manufacture are described corresponding to immutable configuration of memory devices. An example memory includes a memory bank including a first portion and a second portion, the second portion configured to store configuration information that specifies whether the first portion is immutable; and a controller coupled to the memory bank, the controller configured to determine whether to prevent data from being written to the first portion based on the configuration information.
Claims20
Memory comprising:
- a memory bank including a first portion and a second portion, the second portion configured to store configuration information that specifies whether the first portion is immutable;
- and
- a controller coupled to the memory bank, the controller configured to determine whether to prevent data from being written to the first portion based on the configuration information.
An apparatus comprising:
- memory including a first portion of memory and a second portion, the second portion configured to store configuration information that specifies whether the first portion is immutable;
- and
- processing circuitry configured to:
- obtain the configuration information from the memory;
- store the configuration information in a register;
- and
- based on an operation directed to the first portion of the memory, send a response that specifies whether to prevent the operation to the first portion of the memory based on the configuration information.
An apparatus comprising:
- memory including a first portion of memory and a second portion, the second portion configured to store configuration information that specifies whether the first portion is immutable;
- and
- a memory controller to at least one of instantiate or execute computer readable instructions to:
- based on an instruction corresponding to a write operation to write data to a location of the memory, output an alert including the location of the memory;
- and
- based on a response to the alert, determine whether to prevent the write operation to the location of the memory.
