Introduction of EEPROM for DIMM (SPD)

DIMMs for Data center/server, DIMMs for Client

ABLIC provides JEDEC-compliant Serial Presence Detect (SPD) EEPROMs for DDR4 and DDR5 DIMMs (DRAM modules). ABLIC also provides a lineup of SPD EEPROMs with temperature sensors ideal not only for client, but also for data centers and servers, which support the development of a wide variety of DIMMs.

1. Versatility with all DIMMs

ABLIC's SPD EEPROMs comply with the SPD5118/TSE2004B2/EE1004-1 JEDEC standard.
ABLIC‘s lineup of SPD EEPROMs are available for every application, so it is safe to use in the development of virtually any DIMM.

2. EEPROM-based technology integration for optimal functionality

ABLIC, a Japanese analog semiconductor specialist, has started production for DIMMs based on EEPROM technology.
ABLIC continues to provide SPD EEPROMs with ideal functions for each DDR generation, by integrating the temperature sensor and communication technologies cultivated in-house.
