Gusto-2 Ultra-Low Power NVM IP for Code Storage
Remote wireless sensors for monitoring health and fitness, home automation, and securityGusto-2 is the second generation of Kilopass code storage antifuse non-volatile memory (NVM) intellectual property (IP) that serves a new emerging class of small ultra low-power, one-chip designs. Single chip systems must run for years on a coin cell battery or harvest energy for operation. These designs cannot accept the shadow SRAM leakage in addition to the power of the off-chip serial EEPROM or flash. Such designs need an on-chip NVM: (1) that has near zero standby current; (2) that has the area, active and standby power equal to or better than the shadow SRAM it replaces; (3) support code storage capacities ranging from 32kB to 128kB; (4) has sufficient bandwidth to support execute-in-place operation.
Ultra-low power system-on-chip (SoC) designs in this category perform functions such as
- Remote wireless sensors for monitoring health and fitness, home automation, and security
- Near-field communications (NFC) for digital wallet, wireless financial transactions, electronic identification driver’s license, passport, fare collection, and others as well as
- Applications serving the emerging market of Internet of things.
Gusto-2 will take up a less than a quarter of the designer’s total chip area and power budget. Gusto-2 uses significantly less standby power than the shadow SRAM, consumes less active power than the shadow SRAM and serial Flash/EEPROM it replaces, in a die area that is equivalent to shadow SRAM alone. Gusto-2 delivers 400MB/s throughput, sufficient to enable efficient execute-in-place operation.
