Embodiment 1

[0029] figure 1 It is a schematic structural diagram of a memory in Embodiment 1 of the present invention, which can be applied to any device, for example, a neuromorphic chip, a traditional chip, and the like. Such as figure 1 As shown, the memory 10 provided in this embodiment includes: a connected non-volatile memory unit 100 and a refresh circuit 200 . Wherein, the refresh circuit 200 is used for reading the storage data in the non-volatile storage unit 100 and writing the storage data back to the non-volatile storage unit 100 .

[0030] The non-volatile memory unit 100 may include but not limited to one or more of FLASH flash memory, phase change memory, ferroelectric memory FRAM, resistive memory RRAM, magnetic memory MRAM, spin memory STT-RAM and optical memory .

[0031] The refresh circuit 200 is used to refresh the stored data in the non-volatile memory unit 100, read the stored data in the non-volatile memory unit 100, and write the read stored data back to the n...

Embodiment 2

[0061] Figure 4 It is a schematic structural diagram of a neuromorphic chip in Embodiment 2 of the present invention, which is applicable to neural network computing. Such as Figure 4 As shown, the neuromorphic chip 1 provided in this embodiment includes: at least one memory 10 described in any embodiment of the present invention (one memory 10 is shown in the figure).

[0062] have to be aware of is, Figure 4 The shown neuromorphic chip is only an example showing that the neuromorphic chip includes the memory 10 and the neuron computing core 50 , and does not specifically limit the structure of the neuromorphic chip.

[0063] Optionally, one neuromorphic chip 1 may include one or more memories 10 . When a neuromorphic chip 1 includes only one memory 10 of the disclosed embodiment, the stored data in the memory 10 can be shared by multiple neuron computing cores; when a neuromorphic chip 1 includes multiple memories 10 , the stored data in each memory 10 can be used ind...

Abstract

The embodiment of the invention discloses a memory and a neuromorphic chip. The memory comprises a nonvolatile memory unit and a refresh circuit which are connected with each other; the refreshing circuit is used for reading the storage data in the nonvolatile storage unit and writing the storage data back to the nonvolatile storage unit. Under the condition that the area of the nonvolatile storage unit is fixed, the storage device increases the storage duration of the storage data in the nonvolatile storage unit, and the technical effect of flexibly adjusting the storage duration of the datais achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of chip technology, and in particular, to a memory and a neuromorphic chip. Background technique [0002] According to the length of data storage, memory can be divided into volatile memory and non-volatile memory. Among them, the data in the volatile memory cannot be retained for a long time after power failure, and the data in the non-volatile memory can be retained for a long time after power failure. However, when the non-volatile memory shrinks to tens of nanometers or even smaller, its non-volatility is greatly challenged, and the non-volatile memory often needs to make a compromise between storage density and data retention time. Contents of the invention [0003] Embodiments of the present invention provide a memory and a neuromorphic chip, which can flexibly adjust the data storage duration according to actual application conditions, and realize long-term data storage by means of circ...
