Execute-in-Place: Getting More from Embedded NVM

With XiP, a processor can execute code directly from non-volatile memory, without first copying it into SRAM. Fast embedded NVM like ReRAM or RRAM can make this approach particularly useful, helping reduce SRAM requirements, power consumption and system wake-up time.

Why Physical AI Needs a New Generation of Embedded Memory

Weebit ReRAM emerging approaches such as in-memory computing (IMC) seek to perform certain AI operations directly within memory arrays, reducing the need to move data between memory and compute for applications where power efficiency and real-time responsiveness are critical.

Weebit Nano raises $15 million via strongly supported SPP

Weebit Nano, a leading developer of advanced memory technologies for the global semiconductor industry, has successfully raised approximately $15 million via a strongly supported Share Purchase Plan (SPP) to existing shareholders.

When Memory Shortages Change Architecture Decisions

For decades, the choice between embedded and external Non-Volatile Memory (NVM) in semiconductor designs has been straightforward. External memory, such as EEPROM, NOR Flash, or NAND Flash, offered lower cost per bit and greater flexibility, making a two-die architecture the default choice across a wide range of applications. That assumption is now being challenged.
