A 40-nm Embedded SG-MONOS Flash Macro for High-End MCU Achieving 200-MHz Random Read Operation and 7.91-Mb/mm² Density With Charge-Assisted Offset Cancellation Sense Amplifier

A 0.11pJ/bit read energy embedded NanoBridge non-volatile memory and its integration in a 28 nm 32 bit RISC-V microcontroller units

“…These integral computing chips facilitate the functionality of a multitude of devices, ranging from everyday gadgets like smart watches 1) to more advanced systems pivotal in emerging applications like Internet of Things (IoT) edge and cloud computing, 2) Augmented Reality, 3) Virtual Reality, 4) autonomous vehicles, 5) and smart healthcare devices. 6) In the heart of the MCUs, there is a type of memory known as read only memory (ROM) mostly using an embedded NOR Flash (eFLASH), 7) which is responsible for storing the instructions that the MCUs need to function. However, with the rise of applications requiring quick responses and efficient energy use, such as IoT edge devices and cloud computing platforms, the eFLASH is hitting a wall due to its relatively high energy consumption and physical scaling limits.…”

An Ultra-Low-Power Reconfigurable Power-On Reset for Multi-Supply Voltages Applications

“…Introduction: Modern high-performance microprocessors usually require different functional modules working in individual domains to maximize the performance and reduce power dissipation [1]. To avoid the floating states of memory and registers in digital system causing undesired initial behavior during the ramp-up [2], a power-on-reset (POR) circuit with brown-out-reset (BOR) function is needed to ensure them a known or initial-state behaviour.…”
