SiPROM provides the broadest range of process node coverage - from 130nm down to 55nm. Densities up to 512 Kbits per macro are available and multiple macros can be used for higher memory capacity, making SiPROM an ideal and field-programmable replacement for masked ROM and, in certain applications, external Flash memory. Designers can choose between four read modes to trade off memory density, read access time, enhanced reliability and enhanced security, and different read modes may be combined in the same macro.
SiPROM macros contain a built-in charge pump, which provides the voltage necessary to program the memory in the field after the chip is packaged. Alternately, programming voltage may be supplied externally through a pad on the chip.
Other SiPROM features include:
SiPROM uses include HDCP encryption keys, analog trim and calibration, boot code and firmware storage, Chip ID, RFID, and other mobile and wireless, medical, and automotive applications.
SiPROM macros are ideally suited to a wide range of applications including:
