ZMD U630H16 HardStore 2K x 8 nvSRAM Datasheet
The ZMD U630H16 is a 2K x 8 bit nvSRAM device that integrates a fast static RAM with an electrically erasable PROM (EEPROM). It operates in two modes determined by the NE pin: SRAM mode for standard read/write operations and nonvolatile mode for transferring data between SRAM and EEPROM. The device supports unlimited recall cycles from EEPROM to restore data after power loss.

Questions answered in these manuals
How is the operating mode selected?
The operating mode is determined by the state of the NE pin, which selects between SRAM mode and nonvolatile mode.
Can data be recalled from EEPROM after power loss?
Yes, an automatic RECALL occurs on Power Up when the voltage exceeds a specific threshold, and unlimited recall cycles are supported.
What is the memory size of the U630H16?
The U630H16 provides 2048 × 8 bits of static RAM.
