Systems and/or methods that facilitate error correction of data are presented. An error correction code (ECC) control component facilitates enabling or disabling error correction of data being written to or read from memory, such as flash memory, based on ECC indicator data associated with a piece of data. The ECC control component can analyze data, parity code, and/or indicator data associated with the incoming data and/or data stored in the memory location where the incoming data is to be written to determine whether parity code can be written for the incoming data and/or whether error correction can be enabled with respect to the incoming data. Error correction can be enabled when an indicator bit associated with the data is unprogrammed (e.g., bit set to '1' state) and can be disabled by programming the indicator bit (e.g., bit set to a '0' state).

Error correction coding in flash memory devices

Systems and methods of detecting an auto-boot mode and booting data from a serial peripheral interface to a processor without the need of a read instruction utilizing a serial peripheral interface having an auto-boot mode detector are provided. In one embodiment, a serial peripheral interface comprises a serial processing component configured to serially communicate data between the processor and at least two peripherals, and an auto-boot component operably coupled to the serial processing component, comprising an auto-boot mode detector configured to determine whether a boot mode exists based on detecting whether serial input data is received during a predetermined wait state, and configured to selectively boot data to a start address associated with the processor based on the boot mode determination.

Systems and methods of addressing two or more banks of memory utilizing a single-bank serial peripheral interface and an at least three-byte address protocol are provided. In one embodiment, a serial peripheral interface comprises a serial processing component configured to address one of the memory banks using the three-byte addressing scheme, and to write data to or read data from the addressed bank, and a bank register pointer component coupled to the serial processing component, the pointer component comprising two or more bank register pointers associated with respective memory banks, and configured to select one of the memory banks based on the two or more bank register pointers, wherein the bank register pointer component selects one of the two or more memory banks, and the serial processing component writes data to or reads data from the selected bank of memory according to the three-byte addressing scheme.
