6.10 Flash Memory
6.10.1 Flash Memory Configuration
Flash Bank: A separate block of logic consisting of 1 to 16 sectors. Each flash bank normally has a
customer-OTP and a TI-OTP area. These flash sectors share input/output buffers, data paths, sense
amplifiers, and control logic.
Flash Sector: A contiguous region of flash memory which must be erased simultaneously due to physical
construction constraints.
Flash Pump: A charge pump which generates all the voltages required for reading, programming, or
erasing the flash banks.
Flash Module: Interface circuitry required between the host CPU and the flash banks and pump module.
