The invention discloses a single-event-proximity-effect-resistant static storage unit of a
physical space interleaving type. The static storage unit comprises a
transistor of a storage unit A and a
transistor of a storage unit B, wherein the
transistor of storage unit A is composed of a first access transistor AMG1 of the storage unit A, a second access transistor AMG2 of the storage unit A, a first pull-up transistor AMP1 of the storage unit A, a second pull-up transistor AMP2 of the storage unit A, a first pull-down transistor AMN1 of the storage unit A and a second pull-down transistor AMN2 of the storage unit A, which are arranged on a
silicon substrate; and the transistor of the storage unit B is composed of a first access transistor BMG1 of the unit B, a second access transistor BMG2 of the unit B, a first pull-up transistor BMP1 of the unit B, a second pull-up transistor BMP2 of the unit B, a first pull-down transistor BMN1 of the unit B and a second pull-down transistor BMN2 of the unit B, which are arranged on the
silicon substrate. Proximity effect can be effectively reduced by adopting the invention, and therefore, the critical charges of SEU (
Single Event Upset) of the storage units are enlarged to enhance the single event resistance.
